What are common pitfalls when using mod_rewrite in PHP?

Common pitfalls when using mod_rewrite in PHP include incorrect regular expressions, not enabling mod_rewrite in the server configuration, and not properly handling rewrite rules for different environments (e.g., local development vs. production). To solve these issues, make sure to double-check your regular expressions, enable mod_rewrite in your server configuration, and create separate .htaccess files for different environments. 

// Example of enabling mod_rewrite in .htaccess file
<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /
    RewriteRule ^index\.php$ - [L]
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule . /index.php [L]
</IfModule>
