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

警告

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.
