yaml_parse - Parse a YAML stream

SYNOPSIS
mixed yaml_parse (string $input, [int $pos], [int &$ndocs], [array $callbacks]) DESCRIPTION
Convert all or part of a YAML document stream to a PHP variable. PARAMETERS
o $input - The string to parse as a YAML document stream. o $pos - Document to extract from stream ( -1 for all documents, 0 for first document, ...). o $ndocs - If $ndocs is provided, then it is filled with the number of documents found in stream. o $callbacks - Content handlers for YAML nodes. Associative array of YAML tag => callable mappings. See parse callbacks for more details. RETURN VALUES
Returns the value encoded in $input in appropriate PHP type or FALSE on failure. If $pos is -1 an array will be returned with one entry for each document found in the stream. EXAMPLES
Example #1 yaml_parse(3) example <?php $yaml = <<<EOD --- invoice: 34843 date: "2001-01-23" bill-to: &id001 given: Chris family: Dumars address: lines: |- 458 Walkman Dr. Suite #292 city: Royal Oak state: MI postal: 48046 ship-to: *id001 product: - sku: BL394D quantity: 4 description: Basketball price: 450 - sku: BL4438H quantity: 1 description: Super Hoop price: 2392 tax: 251.420000 total: 4443.520000 comments: Late afternoon is best. Backup contact is Nancy Billsmer @ 338-4338. EOD; $parsed = yaml_parse($yaml); var_dump($parsed); ?> The above example will output something similar to: array(8) { ["invoice"]=> int(34843) ["date"]=> string(10) "2001-01-23" ["bill-to"]=> &array(3) { ["given"]=> string(5) "Chris" ["family"]=> string(6) "Dumars" ["address"]=> array(4) { ["lines"]=> string(34) "458 Walkman Dr. Suite #292" ["city"]=> string(9) "Royal Oak" ["state"]=> string(2) "MI" ["postal"]=> int(48046) } } ["ship-to"]=> &array(3) { ["given"]=> string(5) "Chris" ["family"]=> string(6) "Dumars" ["address"]=> array(4) { ["lines"]=> string(34) "458 Walkman Dr. Suite #292" ["city"]=> string(9) "Royal Oak" ["state"]=> string(2) "MI" ["postal"]=> int(48046) } } ["product"]=> array(2) { [0]=> array(4) { ["sku"]=> string(6) "BL394D" ["quantity"]=> int(4) ["description"]=> string(10) "Basketball" ["price"]=> int(450) } [1]=> array(4) { ["sku"]=> string(7) "BL4438H" ["quantity"]=> int(1) ["description"]=> string(10) "Super Hoop" ["price"]=> int(2392) } } ["tax"]=> float(251.42) ["total"]=> float(4443.52) ["comments"]=> string(68) "Late afternoon is best. Backup contact is Nancy Billsmer @ 338-4338." } NOTES
Warning Processing untrusted user input with yaml_parse(3) is dangerous if the use of unserialize(3) is enabled for nodes using the !php/object tag. This behavior can be disabled by using the yaml.decode_php ini setting. SEE ALSO
