[, int &$ndocs
[, array $callbacks = NULL
]]] ) : mixedConvert all or part of a YAML document stream read from a URL to a PHP variable.
参数
-
url -
urlshould 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. -
pos -
Document to extract from stream (-1 for all documents, 0 for first document, ...).
-
ndocs -
If
ndocsis provided, then it is filled with the number of documents found in stream. -
callbacks -
Content handlers for YAML nodes. Associative array of YAML tag => callable mappings. See parse callbacks for more
返回值
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.
注释
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.
