`<?php
$addr = array(
"given" => "Chris",
"family"=> "Dumars",
"address"=> array(
"lines"=> "458 Walkman Dr.
Suite #292",
"city"=> "Royal Oak",
"state"=> "MI",
"postal"=> 48046,
),
);
$invoice = array (
"invoice"=> 34843,
"date"=> "2001-01-23",
"bill-to"=> $addr,
"ship-to"=> $addr,
"product"=> array(
array(
"sku"=> "BL394D",
"quantity"=> 4,
"description"=> "Basketball",
"price"=> 450,
),
array(
"sku"=> "BL4438H",
"quantity"=> 1,
"description"=> "Super Hoop",
"price"=> 2392,
),
),
"tax"=> 251.42,
"total"=> 4443.52,
"comments"=> "Late afternoon is best. Backup contact is Nancy Billsmer @ 338-4338.",
);
// generate a YAML representation of the invoice
$yaml = yaml_emit($invoice);
var_dump($yaml);
// convert the YAML back into a PHP variable
$parsed = yaml_parse($yaml);
// check that roundtrip conversion produced an equivalent structure
var_dump($parsed == $invoice);
?>`

The above example will output something similar to:

    string(631) "---
    invoice: 34843
    date: "2001-01-23"
    bill-to:
