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

number of documents found in stream.
callbacksContent handlers for YAML nodes. Associative array of YAML tag => callable mappings. See parse callbacks for more details.

PHP type 或者在失败时返回 false. If pos is -1 an
array will be returned with one entry for each document found
in the stream.
Processing untrusted user input with yaml_parse_file()
is dangerous if the use of unserialize() is enabled for
nodes using the !php/object tag. This behavior can be
disabled by using the yaml.decode_php ini setting.
