How can one exclude certain files or folders from the rewrite rule in PHP?

To exclude certain files or folders from a rewrite rule in PHP, you can use the RewriteCond directive in the .htaccess file to specify conditions under which the rewrite rule should be applied. You can use regular expressions to match specific files or folders and exclude them from the rewrite rule.

RewriteEngine On
RewriteCond %{REQUEST_URI} !^/excluded-folder/.*$
RewriteCond %{REQUEST_URI} !^/excluded-file.php$
RewriteRule ^(.*)$ index.php?url=$1 [QSA,L]
