public static function UrlHelper::isExternal in Service Container 7.2

Same name and namespace in other branches

7 lib/Drupal/Component/Utility/UrlHelper.php \Drupal\Component\Utility\UrlHelper::isExternal()

Determines whether a path is external to Drupal (e.g. http://example.com).

If a path cannot be assessed by Drupal's menu handler, then we must treat it as potentially insecure.

Parameters

string $path: The internal path or external URL being linked to, such as "node/34" or "http://example.com/foo".

Return value

bool TRUE or FALSE, where TRUE indicates an external path.

File

lib/Drupal/Component/Utility/UrlHelper.php, line 215: Contains \Drupal\Component\Utility\UrlHelper.

Class

UrlHelper: Helper class URL based methods.

Namespace

Drupal\Component\Utility

Code

public static function isExternal($path) {
  $colonpos = strpos($path, ':');

  // Avoid calling drupal_strip_dangerous_protocols() if there is any slash
  // (/), hash (#) or question_mark (?) before the colon (:) occurrence - if
  // any - as this would clearly mean it is not a URL. If the path starts with
  // 2 slashes then it is always considered an external URL without an
  // explicit protocol part.
  return strpos($path, '//') === 0 || $colonpos !== FALSE && !preg_match('![/?#]!', substr($path, 0, $colonpos)) && static::stripDangerousProtocols($path) == $path;
}
