How can I use .htaccess to create pretty URLs from query parameters?

Creating Pretty URLs with .htaccess

Question: How can I transform a URL from http://localhost/index.php?user=1&action=update to http://localhost/user/1/update using .htaccess?

Answer:

To achieve this transformation, you can use the following .htaccess rules:

Options +FollowSymLinks
RewriteEngine On

RewriteRule ^user/([0-9]*)/([a-z]*)$ ./index.php?user=&action=

Explanation:

1. Rewrite Groups: The parentheses within the RewriteRule group the user id ([0-9]*) and action ([a-z]*).
2. Pattern Matching: The pattern ^user/([0-9]*)/([a-z]*)$ matches URLs like user/1/update.
3. Replacement String: The ./index.php?user=$1&action=$2 specifies that the extracted user id ($1) and action ($2) should be passed as query parameters to index.php.

To Access Parameters in PHP:

To access the extracted parameters in your PHP code, use the following:

<code class="php"><?php
echo "user id:" . $_GET['user'];
echo "<br>action:" . $_GET['action'];
?></code>

Note:

• The [0-9]* and [a-z]* patterns specify that the user id should only contain numbers and the action should only contain lowercase characters, respectively.
• Grouping and regular expressions allow for more specific and secure URL transformations compared to using (.*), which accepts almost anything.
