Common functions that many Drupal modules will need to reference.

Code

function drupal_html_class($class) {
  // The output of this function will never change, so this uses a normal
  // static instead of drupal_static().
  static $classes = array();

  if (!isset($classes[$class])) {
    $classes[$class] = drupal_clean_css_identifier(drupal_strtolower($class));
  }
  return $classes[$class];
