url

url($path = NULL, array $options = array())
Generate a URL.
When creating links in modules, consider whether l() could be a better alternative than url().
Parameters
$path The Drupal path being linked to, such as "admin/content", or an existing URL like "http://drupal.org/". The special path '<front>' may also be given and will generate the site's base URL.
$options An associative array of additional options, with the following keys:
- 'query': An array of query key/value-pairs (without any URL-encoding) to append to the link.
- 'fragment': A fragment identifier (or named anchor) to append to the link. Do not include the leading '#' character.
- 'absolute': Defaults to FALSE. Whether to force the output to be an absolute link (beginning with http:). Useful for links that will be displayed outside the site, such as in a RSS feed.
- 'alias': Defaults to FALSE. Whether the given path is a URL alias already.
- 'external': Whether the given path is an external URL.
- 'language': An optional language object. If the path being linked to is internal to the site, $options['language'] is used to look up the alias for the URL. If $options['language'] is omitted, the global $language will be used.
- 'https': Whether this URL should point to a secure location. If not defined, the current scheme is used, so the user stays on http or https respectively. TRUE enforces HTTPS and FALSE enforces HTTP, but HTTPS can only be enforced when the variable 'https' is set to TRUE.
- 'base_url': Only used internally, to modify the base URL when a language dependent URL requires so.
- 'prefix': Only used internally, to modify the path when a language dependent URL requires so.
Return value
A string containing a URL to the given path.
