We are going to use .htaccess (hypertext access) rewrite rules to achieve these clean URLs. The .htaccess file provide a directory level configuration that is supported by several web servers such as Apache.
Our post for today covers the following contents:
1.0 Existing Apache .htaccess Rewriterule Examples
2.0 Four Apache .htaccess Rewriterule Example Codes
2.1 URL with two parameters: letter and number
2.2 URL with one parameter: name of the PHP file

2.4 URL with one parameter: numbers with underscore
3.0 Complete .htaccess Code Used

2.0 FOUR APACHE .HTACCESS REWRITERULE EXAMPLES
Our .htaccess and PHP files are placed in the “htaccess-clean-urls” folder.
.htaccess uses regular expressions to identify which PHP file will be loaded on the browser, based on the parameter(s) given.
We have 4 example codes below. Please note that “localhost” refers to “yoursite.com”. I was using my local server when I did these examples so please keep it in mind.
2.1 URL with two parameters: letter and number
This URL:
Is equivalent to this clean URL:
.htaccess code used:
RewriteRule ^([a-z]+)\/([0-9]+)\/?$ parameter_letter_and_number.php?param=$1¶m2=$2 [NC]
|
PHP page used: parameter_letter_and_number.php
<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>Clean URL with .htaccess by http:

<body>
<h1>Parameter: Letter and Number ONLY. This is parameter_letter_and_number.php</h1>
<?php
echo "PARAMETER VALUE 1: " . $_REQUEST['param'];
echo "<br />";
echo "PARAMETER VALUE 2: " . $_REQUEST['param2'];
?>
</body>
</html>

The following codes are the ones we used in the examples above, put into one .htaccess file.
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteRule ^([a-z]+)\/([0-9]+)\/?$ parameter_letter_and_number.php?param=$1¶m2=$2 [NC]
RewriteRule ^([a-z]+)\/?$ $1.php [NC]
