How can PHP developers ensure that specific functions or features on a website are not affected by .htaccess rules?

When using .htaccess rules to control access or redirect URLs on a website, PHP developers can ensure that specific functions or features are not affected by adding conditions to the .htaccess rules that exclude certain URLs or directories. By specifying exceptions in the .htaccess file, developers can allow certain URLs to bypass the rules and function as intended without interference.

// Example of adding exceptions in .htaccess file to allow specific URLs to bypass rules
<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond %{REQUEST_URI} !^/specific-functionality/ [NC]
    RewriteRule ^(.*)$ index.php [L]
</IfModule>
