yaml_parse_url - Parse a Yaml stream from a URL

SYNOPSIS
       mixed yaml_parse_url (string  $url, [int  $pos], [int  &$ndocs], [array	$callbacks])

DESCRIPTION
	Convert all or part of a YAML document stream read from a URL to a PHP variable.

PARAMETERS
	      o $url
		-$url  should  be of the form "scheme://...". PHP will search for a protocol handler (also known as a wrapper) for that scheme. If
		no wrappers for that protocol are registered, PHP will emit a notice to help you track potential problems in your script and  then
		continue as though filename specifies a regular file.

	      o $pos
		- Document to extract from stream ( -1 for all documents, 0 for first document, ...).

	      o $ndocs
		- If $ndocs is provided, then it is filled with the number of documents found in stream.

	      o $callbacks
		- Content handlers for YAML nodes. Associative array of YAML tag => callable mappings. See parse callbacks for more

RETURN VALUES
	Returns  the  value  encoded in $input in appropriate PHP type or FALSE on failure. If $pos is -1 an array will be returned with one entry
       for each document found in the stream.

NOTES
       Warning

	       Processing untrusted user input with yaml_parse_url(3) is dangerous if the use of unserialize(3) is enabled  for  nodes	using  the
	      !php/object tag. This behavior can be disabled by using the yaml.decode_php ini setting.
