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
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.
posDocument to extract from stream (-1 for all documents, 0 for first document, ...).
ndocs
If ndocs is provided, then it is filled with the
number of documents found in stream.
callbacksContent handlers for YAML nodes. Associative array of YAML tag => callable mappings. See parse callbacks for more
Returns the value encoded in input in appropriate
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_url() 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.
