This post explains how to create SEO friendly URL with dynamic content using PHP and .htaccess mod redirection. Friendly URLs improves your site search engines ranking. Before trying this you have to enable mod_rewrite.so module at httpd.conf. It's simple just few lines of PHP code converting title data to clean URL format.

Database
Sample database blog table columns id, title, body and url.

CREATE TABLE blog
(
id INT PRIMARY KEY AUTO_INCREMENT,
title TEXT UNIQUE,
body TEXT,
url TEXT UNIQUE,
);

Publish.php

<?php
include(‘db.php’);
function string_limit_words($string, $word_limit)
{
$words = explode(‘ ‘, $string);
return implode(‘ ‘, array_slice($words, 0, $word_limit));
}

if($_SERVER["REQUEST_METHOD"] == “POST“)
{
$title=mysql_real_escape_string($_POST['title']);
$body=mysql_real_escape_string($_POST['body']);
$title=htmlentities($title);
$body=htmlentities($body);
$date=date(“Y/m/d”);
//Title to friendly URL conversion
$newtitle=string_limit_words($title, 6); // First 6 words
$urltitle=preg_replace(‘/[^a-z0-9]/i’,‘ ‘, $newtitle);
$newurltitle=str_replace(” “,“-”,$newtitle);
$url=$date.’/’.$newurltitle.’.html’; // Final URL
//Inserting values into my_blog table
mysql_query(“insert into blog(title,body,url) values(‘$title’,'$body’,'$url’)”);
}
?>
//HTML Part
<form method=”post” action=”">
Title:
<input type=”text” name=”title”/>
Body:
<textarea name=”body”></textarea>
<input type=”submit” value=” Publish ”/>
</form>

Article.php

<?php
include(‘db.php’);
if($_GET['url'])
{
$url=mysql_real_escape_string($_GET['url']);
$url=$url.’.html’; //Friendly URL
$sql=mysql_query(“select title,body from blog where url=’$url’”);
$count=mysql_num_rows($sql);
$row=mysql_fetch_array($sql);
$title=$row['title'];
$body=$row['body'];
}
else
{
echo ’404 Page.’;
}
?>
//HTML Part
<body>
<?php
if($count)
{
echo ”<h1>$title</h1><div class=’body’>$body</div>”;
}
else
