How can the use of .htaccess files impact PHP scripts and potentially cause server errors?

Using incorrect configurations in .htaccess files can potentially cause server errors for PHP scripts by overriding PHP settings or blocking access to necessary files. To avoid this, ensure that the .htaccess file is properly configured and does not interfere with PHP scripts.

// Example of a properly configured .htaccess file to avoid server errors for PHP scripts
<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /
    RewriteRule ^index\.php$ - [L]
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule . /index.php [L]
</IfModule>
