Answer 1

Use PHP's filesystem functions and edit it just like any other file.

However, it will only affect requests after the current one, not the one that makes the change. If this matters, have PHP do the same thing as the new .htaccess would.

Answer 2

I am guessing you're trying to rewrite URLs dynamically, if so, there is another approach you can take.

Forward every request to rewrite.php?req=request (through one simple rewrite in the .htaccess) RewriteRule ^(.*?)$ rewrite.php?req=$1

This would then eg rewrite home.php to rewrite.php?req=home.php

Now you can access the relevant request you want, in this case home.php , you could then act on this based on your settings. eg

<?php
$req = $_POST['req']; // need to sanitize this obv

if($option1) {
    // do something
} else if ($option2) {
    // something else
}
?>

Hope that helps!
