yaml_parse_file — Parse a YAML stream from a file

说明

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

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

参数

filename: Path to the 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 details.

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_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.
