function cf_adjust_url in Common Functionality 7.2

Fix relative url pulled from the remote server.

This url is turned into an absolute url.

@see: cf_adjust_urls()

Parameters

string $url: The URL to change.

string $server: The hostname or ip address of the server to use when generating absolute urls. This must not contain the 'http://' prefixes nor the suffixes such as '/' or ':80'.

string $relative_path: all relative paths will have this prepended to the absolute url.

string $scheme: (optional) The 'http' at the front of most urls. A common alternative is 'https'.

string $suffix: (optional) The suffix to prepend to the url. Most cases this should be '/', but if the links are being cached on a different server and a different sub-path, then this must be used.

int $port: (optional) The port number of the web-server. In almost all cases this should be 80. If $schema is set to 'https', then normally this should instead be 443.

Return value

string|bool The new string if it was successfully altered and FALSE otherwise.
