What are common issues when trying to delete .htaccess files using FTP programs?

Common issues when trying to delete .htaccess files using FTP programs include insufficient permissions or the file being in use by the server. To solve this issue, you can try changing the permissions of the .htaccess file to allow deletion or restart the server to release the file.

// Change file permissions to allow deletion
chmod('.htaccess', 0777);

// Delete the .htaccess file
unlink('.htaccess');
?>
