public static function UrlHelper::parse in Service Container 7.2

Same name and namespace in other branches

7 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.

Code

public static function parse($url) {
  $options = array(
    'path' => NULL,
    'query' => array(),
    'fragment' => '',
  );

  // External URLs: not using parse_url() here, so we do not have to rebuild
  // the scheme, host, and path without having any use for it.
  if (strpos($url, '://') !== FALSE) {

    // Split off everything before the query string into 'path'.
    $parts = explode('?', $url);

    // Don't support URLs without a path, like 'http://'.
    list(, $path) = explode('://', $parts[0], 2);
    if ($path != '') {
      $options['path'] = $parts[0];
    }

    // If there is a query string, transform it into keyed query parameters.
    if (isset($parts[1])) {
      $query_parts = explode('#', $parts[1]);
      parse_str($query_parts[0], $options['query']);

      // Take over the fragment, if there is any.
      if (isset($query_parts[1])) {
        $options['fragment'] = $query_parts[1];
      }
    }
  }
  else {

    // parse_url() does not support relative URLs, so make it absolute. E.g. the
    // relative URL "foo/bar:1" isn't properly parsed.
    $parts = parse_url('http://example.com/' . $url);

    // Strip the leading slash that was just added.
    $options['path'] = substr($parts['path'], 1);
    if (isset($parts['query'])) {
      parse_str($parts['query'], $options['query']);
    }
    if (isset($parts['fragment'])) {
      $options['fragment'] = $parts['fragment'];
    }
  }
