(PECL yaml >= 0.4.0)

yaml_parse_url — Parse a Yaml stream from a URL

说明

yaml_parse_url ( string $url [, int $pos = 0 [, int &$ndocs [, array $callbacks = NULL ]]] ) : mixed

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

参数

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.

pos

Document 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.

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

Warning

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.
