Remove query strings from static resources drupal

template.php

<?php

/**
* Implements template_process_html().
*/

// Remove Query Strings from CSS filenames (CacheBuster)
function MYTHEME_process_html(&$variables) {
  $variables['styles'] = preg_replace('/\.css\?.*"/','.css"', $variables['styles']);
}

?>

Very handy! The regex is greedy, though, which means it it keeps matching until the last quote it can find. Here's what I changed it to:

$variables['styles'] = preg_replace('/\.css\?[^"]+/','.css', $variables['styles']);
