The ereg_replace() function searches for string specified by pattern and replaces pattern with replacement if found. The ereg_replace() function operates under the same premises as ereg(), except that the functionality is extended to finding and replacing pattern instead of simply locating it.

Syntax

string ereg_replace ( string $pattern , string $replacement , string $string )

pattern: A POSIX extended regular expression.

replacement: If pattern contains parenthesized substrings, replacement may contain substrings of the form \\digit, which will be replaced by the text matching the digit’th parenthesized substring; \\0 will produce the entire contents of string. Up to nine substrings may be used. Parentheses may be nested, in which case they are counted by the opening parenthesis.

string:The input string.

Example 1

Simple String Replacement, Replacing “five” with “ten” in “I have five mangoes” String:

echo ereg_replace("five", "ten", "I have five mangoes");

Output

From: I have five mangoes
To: I have ten mangoes

Example 2

Simple String Replacement, Replacing “to Buy Mangoes” with “Bananas” in “I like Bananas!” String:

$string = "I like Bananas";
echo ereg_replace("Bananas", "to Buy Mangoes", $string);

Output

From: I like Bananas!
To: I like to Buy Mangoes!

Example 3

Simple String Replacement, Replacing “Windows” with “Mac Ox” in “I like Mac Ox!” String:

$string = "I like Mac Ox!";
$pattern = "Mac Ox";
$replacement = "Windows";
echo ereg_replace($pattern, $replacement, $string);

Output

From: I like Mac Ox!
To: I like Windows!

Example 4

Simple String Replacement, Replacing Spaces between words with Dashes(-) String:

$string = "Learn how to build your own website";
$pattern = " ";
$replacement = "-";
echo ereg_replace($pattern, $replacement, $string);

Output

From: Learn how to build your own website.
To: Learn-how-to-buld-your-own-website.

Example 5

Simple String Replacement, Removing a word from the string:

$string = "How to make money online";
$pattern = " online";
$replacement = "";
echo ereg_replace($pattern, $replacement, $string);

Output

From: How to make money online
To: How to make money

Example 6

Simple String Replacement, highlighting a simple word:

$string = "Learn Php step by step here";
$pattern = "Php";
$replacement = "<font color=red>Php</font>";
echo ereg_replace($pattern, $replacement, $string);

Output

From: Learn Php step by step here
To: Learn Php step by step here

Example 7

Simple String Replacement, highlights the recognized patterns (a good tool for experiments) :

$string = "Learn Php step by step here";
$pattern = "Php";
$replacement = "<font color=red>\\0</font>";
echo ereg_replace($pattern, $replacement, $string);

Output

From: Learn Php step by step here
To: Learn Php step by step here

Example 8

Simple String Replacement, Make all url starts with “http://” clickable:

$string = "Do you want to learn php, please go to http://www.urphp.com";
echo ereg_replace("[a-zA-Z]+://([.]?[a-zA-Z0-9_/-])*", "<a href=\"\\0\">\\0</a>", $string);

Output

From: Do you want to learn php, please go to www.urphp.com
To: Do you want to learn php, please go to www.urphp.com

Example 9

Simple String Replacement, Make all url starts with “www” clickable:

$string = "Do you want to learn php, please go to www.urphp.com";
echo ereg_replace("(^| )(www([.]?[a-zA-Z0-9_/-])*)", "\\1<a href=\"http://\\2\">\\2</a>", $string);

Output

From: Do you want to learn php, please go to www.urphp.com

RSS (most commonly expanded as Really Simple Syndication) is a family of web feed formats used to publish frequently updated works—such as blog entries, news headlines, audio, and video—in a standardized format. An RSS document  includes full or summarized text, plus metadata such as publishing dates and authorship. Web feeds benefit publishers by letting them syndicate content automatically. They benefit readers who want to subscribe to timely updates from favored websites or to aggregate feeds from many sites into one place. RSS feeds can be read using software called an “RSS reader”, “feed reader”, or “aggregator“, which can be web-based, desktop-based, or mobile-device-based.
As RSS files are essentially XML formatted plain text, the RSS file itself is relatively easily read both by automated processes and by humans alike. An example file could have contents such as the following. This could be placed on any appropriate communication protocol for file retrieval, such as http or ftp, and reading software would use the information to present a neat display to the end user.

File format (Syntax)

<?xml version="1.0" encoding="UTF-8" ?>
<rss version="2.0">
<channel>
        <title>RSS Title</title>
        <description>This is an example of an RSS feed</description>

        <item>
                <title>Example entry</title>
                <description>Here is some interesting description.</description>

        </item>

</channel>
</rss>

Lets Create the Rss Feed

First we have to make our map skeleton with some needed stuff (for example database connection), Create a new “rssfeed.php” file and copy and paste the below code:

<?php $host = "localhost"; // host name
$user = "user"; // database user name
$pass = "password"; // database password
$database = "dbname"; // database name
// connecting to database
$connect = @mysql_connect($host,$user,$pass)or die (@mysql_error());
// selecting database
@mysql_select_db($database,$connect) or die (@mysql_error());
?>

$host: leave it default
$user: change it to your database username
$pass: change it to your database password
$database: change it to your database name

Set The Header, Begin the Feed

Now lets add the default headers to your “rssfeed.php”, By default, PHP sends text with an HTML content type. As a result, your aggregator may not recognize it as a valid RSS / XML file. Enter the header() function. We’ll put the following header near the top of our script, before any text gets sent to the client. Copy and paste the below code under the database connecting and selecting code:

<?php
// default header(don't delete)
header("Content-Type: text/xml;charset=iso-8859-1");
echo '<?xml version="1.0" encoding="ISO-8859-1"?>
<rss version="2.0">
<channel>
<link>http://www.yourwebsite.com</link>
<language>en-us</language>
<copyright>Copyright (C) 2011 yourwebsite.com</copyright>
<pubDate>' . date("D, d M Y H:i:s O", time()) . '</pubDate>';
?>

yourwebsite.com: Change this to your website url.
A basic RSS document consists of a channel. Within each channel are items. At minimum, each item requires a title, description and link. In this example, we’re also going to add a publication date.

Retrieve Data From The Database

Here we have simple MySQL query (we take newest articles from “mytable” table), Copy & Paste the below code under the default headers:

<?php
// selecting data from "mytable"
// mytable = your article table name
$query = @mysql_query("SELECT * FROM mytable ORDER BY tblID DESC LIMIT 0,10");
while($row = @mysql_fetch_array($query)){
// [url] = change it to your article title
$title = $row['title'];
// [url] = change it to your article title
$description = $row['description'];
// [url] = change it to your article url
$url = $row['url'];
// [time] = change it to your article date
$date = date("D, d M Y H:i:s O", $row['time']);
?>

mytable: Change this to your table name.
ORDER BY DESC: This is used for showing the latest articles.
LIMIT 0,10: This is used for showing the latest 10 articles.

Building the Feed, Adding Items Without Thumbnail

Now we get to the good stuff: Building the actual feed without thumbnail. We’ll take the code above, and add the following lines.

<?php
echo '<item>';
echo '<title>' . $title . '</title>';
echo '<description>' . $description . '</description>';
echo '<link>' . $link . '</link>';
echo '<guid>' . $link . '</guid>';
echo '<pubDate>' . $date . '</pubDate>';
echo '</item>';
?>

Building the Feed, Adding Items With Thumbnail

Now we get to the good stuff: Building the actual feed with thumbnail. We’ll take the code above, and add the following lines.

<?php
echo '<item>';
echo '<title>' . $title . '</title>';
echo '<description><![CDATA[<img src=' . $avatar . ' width=60 height=60 hspace=0 vspace=0 border=0 align=left /> ' . $description . ' ]]></description>';
echo '<link>' . $link . '</link>';
echo '<guid>' . $link . '</guid>';
echo '<pubDate>' . $date . '</pubDate>';
echo '</item>';
?>

$avatar: Change this to the article thumbnail url.
width-height Write the actula width and height for the thumbnail.

Closing the tags

That’s it we are almost done, just close the while() and <urlset> tags.

} /// closing the while tag
echo '
</urlset>';

and that’s it we are finished!

Putting it all together

<?php
$host = "localhost"; // host name
$user = "user"; // database user name
$pass = "password"; // database password
$database = "dbname"; // database name
// connecting to database
$connect = @mysql_connect($host,$user,$pass)or die (@mysql_error());
// selecting database
@mysql_select_db($database,$connect) or die (@mysql_error());

header("Content-Type: text/xml;charset=iso-8859-1");
echo '<?xml version="1.0" encoding="ISO-8859-1"?>
<rss version="2.0">
<channel>
<link>http://www.yourwebsite.com</link>
<language>en-us</language>
<copyright>Copyright (C) 2011 yourwebsite.com</copyright>
<pubDate>' . date("D, d M Y H:i:s O", time()) . '</pubDate>';

// selecting data from "mytable"
// mytable = your article table name
$query = @mysql_query("SELECT * FROM mytable ORDER BY tblID DESC LIMIT 0,10");
while($row = @mysql_fetch_array($query)){
// [url] = change it to your article title
$title = $row['title'];
// [url] = change it to your article title
$description = $row['description'];
// [url] = change it to your article url
$url = $row['url'];
// [time] = change it to your article date
$date = date("D, d M Y H:i:s O", $row['time']);

echo '<item>';
echo '<title>' . $title . '</title>';
echo '<description><![CDATA[<img src=' . $avatar . ' width=60 height=60 hspace=0 vspace=0 border=0 align=left /> ' . $description . ' ]]></description>';
echo '<link>' . $link . '</link>';
echo '<guid>' . $link . '</guid>';
echo '<pubDate>' . $date . '</pubDate>';
echo '</item>';
}
echo '</urlset>';?>

Lets do a little more

do you want to change www.yourwebsite.com/rssfeed.php to www.yourwebsite.com/rssfeed.xml, it is so easy, just add the below code in your “.htaccess” file:

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule (.*)\.xml(.*) $1.php$2 [nocase]
</IfModule>

Once you added the above code in your “.htaccess” file, the www.yourwebsite.com/rssfeed.php file will be automatically converted into www.yourwebsite.com/rssfeed.xml.

You will have something like this, click here

Feed Validation

When you’re finished, you should ensure that the script validates in the W3C Feed Validation Service

Last but not least you should make the feed available to your users, by placing links and RSS icons on your site.

Another marketing option is to submit the link to Feedburner. Feedburner can help distributing your feed, and provide subscriber and usage statistics.

Sitemaps are a way to tell Google about pages on your site we might not otherwise discover. In its simplest terms, a XML Sitemap—usually called Sitemap, with a capital S—is a list of the pages on your website. Creating and submitting a Sitemap helps make sure that Google knows about all the pages on your site, including URLs that may not be discoverable by Google’s normal crawling process.

Sitemaps are particularly helpful if:

— Your site has dynamic content.
— Your site has pages that aren’t easily discovered by Googlebot during the crawl process—for example, pages featuring rich AJAX or images.
— Your site is new and has few links to it. (Googlebot crawls the web by following links from one page to another, so if your site isn’t well linked, it may be hard for us to discover it.)
— Your site has a large archive of content pages that are not well linked to each other, or are not linked at all.

Google doesn’t guarantee that we’ll crawl or index all of your URLs. However, we use the data in your Sitemap to learn about your site’s structure, which will allow us to improve our crawler schedule and do a better job crawling your site in the future. In most cases, webmasters will benefit from Sitemap submission, and in no case will you be penalized for it.

Google adheres to Sitemap Protocol 0.9 as defined by sitemaps.org. Sitemaps created for Google using Sitemap Protocol 0.9 are therefore compatible with other search engines that adopt the standards of sitemaps.org.

File format

<?xml version="1.0" encoding="utf-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
        <url>
                <loc>http://example.com/</loc>

Lets Create Php Google Sitemap

First we have to make our map skeleton with some needed stuff (for example database connection), Create a new “sitemap.php” file and copy and paste the below code:

$host = "localhost"; // host name
$user = "user"; // database user name
$pass = "password"; // database password
$database = "dbname"; // database name
// connecting to database
$connect = @mysql_connect($host,$user,$pass)or die (@mysql_error());
// selecting database
@mysql_select_db($database,$connect) or die (@mysql_error());

$host: leave it default
$user: change it to your database username
$pass: change it to your database password
$database: change it to your database name

Creating XML

Now lets add the default headers to your “sitemap.php”, copy and paste the below code under the database connecting and selecting code:

// default header(don't delete)
header("Content-Type: text/xml;charset=iso-8859-1");
echo '<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">';

Adding Urls to XML

Here we have simple MySQL query (we take newest articles url and date from “mytable” table), Copy & Paste the below code under the default headers:

// selecting data from "mytable"
// mytable = your article table name
$query = @mysql_query("SELECT * FROM mytable");

while($row = @mysql_fetch_array($query)){
// [url] = article url
$url = $row['url'];
// [time] = article date
$date = date("Y-m-d", $row['time']);

// NO CHANGES BELOW
	echo
    '<url>
     <loc>' . $url .'</loc>
     <lastmod>'. $date .'</lastmod>
     <changefreq>daily</changefreq>
     <priority>0.8</priority>
     </url>
    ';
}
echo '</urlset>';?>

$row['url']; Change this to your article url.
$row['date']; Change this to your article date.

and that’s it we are finished!

Now create a new ‘write-post.php’ file in the admincp folder and Copy & Paste the below code:

<form action="" method="post" name="post">
  <p>Post Name:<br />
  <input name="postName" type="text" size="45" />
  </p>
  <p>Post Author:<br />
    <input name="postUser" type="text" size="45" />
  </p>
  <p>Post Details:<br />
    <textarea name="postDetail" cols="40" rows="15"></textarea>
  </p>
  <input name="post" type="submit" value="Write Post" />
</form>

Creating Codings

Copy & Paste the below code in the ‘write-post.php’:

<?php
//////// Connecting and selecting mysql database
$host = "localhost";  /// use default
$username = "user"; /// write your mysql username
$password = "pass"; /// write your mysql password
$database = "cms"; /// write your mysql database
$connect = @mysql_connect($host, $username, $password) or die (@mysql_error());
$selectdb = @mysql_select_db($database, $connect) or die (@mysql_error());

//////// inserting forms data in mysql database
if(isset($_POST['post'])){
	$postName = $_POST['postName']; /// post name
	$postUser = $_POST['postUser']; /// post author
	$postDetail = $_POST['postDetail']; /// post details
	$postDate = time();  /// post timestamp
	///// checking empty fields
	if(empty($postName) OR empty($postUser) OR empty($postDetail)){
		echo "Sorry, You must fill all the forms!";
	}else{
	//// inserting data in mysql database
	$data = @mysql_query("INSERT INTO posts SET postName='$postName', postUser='$postUser', postDetail='$postDetail', postDate='$postDate'") or die(@mysql_error());

	if($data){echo "Post submitted succesfully";} /// << if data submitted, then show this message
	}
}
?>

Putting it all together (write-post.php)

Managing Posts

Now lets create “manage-post.php” file.

Showing MySql Data

Showing mysql data in “manage-post.php”.

Creating Code

Copy & Paste the below code in the “manage-post.php”

<?php
//////// Connecting and selecting mysql database
$host = "localhost";  /// use default
$username = "user"; /// write your mysql username
$password = "pass"; /// write your mysql password
$database = "cms"; /// write your mysql database
$connect = @mysql_connect($host, $username, $password) or die (@mysql_error());
$selectdb = @mysql_select_db($database, $connect) or die (@mysql_error());

$selectPosts = @mysql_query("SELECT * FROM posts ORDER BY postName ASC"); /// selecting all posts from mysql database

while($showpost = @mysql_fetch_array($selectPosts)){ //// showing mysql data ?>

<?php echo $showpost['postName'];?> - <a href="?action=edit&ID=<?php echo $showpost['postID'];?>">Edit</a> - <a href="?action=delete&ID=<?php echo $showpost['postID'];?>">Delete</a><br /><br />
<?php }?>

Editing a Post

If some click on the “Edit” link, then edit the post…

Creating Coding

Copy and Paste the below code “manage-post.php”.

<?php
if(isset($_POST['update'])){ /// if button submitted
$postName = $_POST['postName']; // get the post name
$postUser = $_POST['postUser']; // get the post user
$postDetail = $_POST['postDetail']; // get the post detail
$postID = $_POST['postID']; // get the post id
/// update the forms data in the mysql database
 $data = @mysql_query("UPDATE posts SET postName='$postName', postUser='$postUser', postDetail='$postDetail' WHERE postID='$postID'") or die(@mysql_error());
/// if data submitted to database
 if($data){echo "  &#8212;  Post updated succesfully, click here to <a href='/admincp/manage-post.php?refresh'>refresh</a>";}
}

$action = $_GET['action']; /// get the action from the url, for example ?action=edit or ?action=delete
$ID = $_GET['ID']; /// get the post id from the url

 if($action == "edit"){ /// if some click on the "Edit" link then edit that link.
 $selectPost = @mysql_fetch_array(@mysql_query("SELECT * FROM posts WHERE postID='$ID'")); /// select all the data of editted post from the database ?>

 <h2>Manage '<?php echo $selectPost['postName'];?>' Post</h2>
 <form action="/admincp/manage-post.php" method="post" name="post">
  <p>Post Name:<br /><input name="postID" type="hidden" value="<?php echo $selectPost['postID'];?>" />
  <input name="postName" type="text" value="<?php echo $selectPost['postName'];?>" size="45" />
  </p>
  <p>Post Author:<br />
    <input name="postUser" type="text"value="<?php echo $selectPost['postUser'];?>" size="45" />
  </p>
  <p>Post Details:<br />
    <textarea name="postDetail" cols="40" rows="15"><?php echo $selectPost['postDetail'];?></textarea>
  </p>
  <input name="update" type="submit" value="Update Post" />
</form>

   <?php }?>

Deleting a Post

If some click on the “Delete” link, then delete the post…

Creating Coding

Copy and Paste the below code “manage-post.php”.

<?php
if(isset($_POST['yes'])){ /// if button submitted
	$postID = $_POST['postID']; // get the post id
	/// delete the data from the mysql databse
		$data = @mysql_query("DELETE FROM posts WHERE postID='$postID'") or die(@mysql_error());
	/// if data deleted from the database
		if($data){echo "  &#8212;  Post Deleted succesfully, click here to <a href='/admincp/manage-post.php?refresh'>refresh</a>";}
}
$action = $_GET['action']; /// get the action from the url, for example ?action=edit or ?action=delete
$ID = $_GET['ID']; /// get the post id from the url
?>

<?php if($action == "delete"){/// if some on click on the "Delete" link then delete that link.
$selectPost = @mysql_fetch_array(@mysql_query("SELECT * FROM posts WHERE postID='$postID'"));  /// select all the data of the post from the database ?>
Are you sure to delete '<?php echo $selectPost['postName'];?>'?<br />
<form action="/admincp/manage-post.php" method="post" name="post">
  <input name="postID" type="hidden" value="<?php echo $selectPost['postID'];?>" />
  <input name="yes" type="submit" value="Yes" /> <input name="No" ONCLICK="history.go(-1)" type="button" value="No" />
</form>
<?php }?>

We are 85% done

Now lets show the posts from the sql database on the main page (eg: in root folder), create a new “index.php” file in the root folder.

Creating Codings

Copy & Paste the below code in “index.php” file.

<?php
$host = "localhost";  /// use default
$username = "username"; /// write your mysql username
$password = "password"; /// write your mysql password
$database = "cms"; /// write your mysql database
$connect = @mysql_connect($host, $username, $password) or die (@mysql_error());
$selectdb = @mysql_select_db($database, $connect) or die (@mysql_error());
/// selecting all posts from mysql database
$selectPosts = @mysql_query("SELECT * FROM posts ORDER BY postName ASC");
//// showing mysql data
while($showpost = @mysql_fetch_array($selectPosts)){  ?>
<?php echo $showpost['postName'];?><br />
<?php }?>

That’s it we are finished!
