Parameters

input: The string to parse as a YAML document stream.
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.

Examples

Example #1 yaml_parse() example

<?php$yaml = <<<EOD---invoice: 34843date: "2001-01-23"bill-to: &id001 given: Chris family: Dumars address: lines: |- 458 Walkman Dr. Suite #292 city: Royal Oak state: MI postal: 48046ship-to: *id001product:- sku: BL394D quantity: 4 description: Basketball price: 450- sku: BL4438H quantity: 1 description: Super Hoop price: 2392tax: 251.420000total: 4443.520000comments: Late afternoon is best. Backup contact is Nancy Billsmer @ 338-4338....EOD;$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() 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.
