  3. 11.x core/lib/Drupal/Component/Utility/UrlHelper.php \Drupal\Component\Utility\UrlHelper::parse()

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 external URL string to parse.

Return value

array An associative array containing:

  • path: The path component of $url. If $url is an external URL, this includes the scheme, authority, and path.
  • query: An array of query parameters from $url, if they exist.
  • fragment: The fragment component from $url, if it exists.
