Description

Finds a pingback server URI based on the given URL.

Checks the xhtml for the rel="pingback" link and x-pingback headers. It does a check for the x-pingback headers first and returns that, if available. The check for the rel="pingback" has more overhead than just the header.

Usage

<?php discover_pingback_server_uri( $url, $deprecated ) ?>

Parameters

$url

(string) (required) URL to ping.

Default: None

$deprecated

(integer) (Not Used.)

Default: None

Return Values

(boolean|string) 

False on failure, string containing URI on success.
