public static UrlHelper::stripDangerousProtocols($uri) Strips dangerous protocols (for example, 'javascript:') from a URI. This function must be called for all URIs within user-entered input prior to being output to an HTML attribute value. It is often called as part of \Drupal\Component\Utility\UrlHelper::filterBadProtocol() or \Drupal\Component\Utility\Xss::filter(), but those functions return an HTML-encoded string, so this function can be called independently when the output needs to be a p

public static UrlHelper::setAllowedProtocols(array $protocols = array()) Sets the allowed protocols. Parameters array $protocols: An array of protocols, for example http, https and irc. File core/lib/Drupal/Component/Utility/UrlHelper.php, line 297 Class UrlHelper Helper class URL based methods. Namespace Drupal\Component\Utility Code public static function setAllowedProtocols(array $protocols = array()) { static::$allowedProtocols = $protocols; }

public static UrlHelper::parse($url) Parses a URL string into its path, query, and fragment components. This function splits both internal paths like node?b=c#d and external URLs like https://example.com/a?b=c#d into their component parts. See RFC 3986 for an explanation of what the component parts are. Note that, unlike the RFC, when passed an external URL, this function groups the scheme, authority, and path together into the path component. Parameters string $url: The internal path or e

public static UrlHelper::isValid($url, $absolute = FALSE) Verifies the syntax of the given URL. This function should only be used on actual URLs. It should not be used for Drupal menu paths, which can contain arbitrary characters. Valid values per RFC 3986. Parameters string $url: The URL to verify. bool $absolute: Whether the URL is absolute (beginning with a scheme such as "http:"). Return value bool TRUE if the URL is in a valid format, FALSE otherwise. File core/lib/Drupal/Component/Utili

public static UrlHelper::isExternal($path) Determines whether a path is external to Drupal. An example of an external path is 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.
