yaml_parse_url — Parse a Yaml stream from a URL
Convert all or part of a YAML document stream read from a URL to a PHP variable.
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.
Document to extract from stream (-1 for all documents, 0 for first document, ...).
If ndocs is provided, then it is filled with the number of documents found in stream.
Returns the value encoded in input in appropriate PHP type. NULL is returned if the input cannot be decoded. If pos is -1 an array will be returned with one entry for each document found in the stream.
