Example #1 Yaml 范例

<?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"=> $addr,    "product"=> array(        array(            "sku"=> "BL394D",            "quantity"=> 4,            "description"=> "Basketball",            "price"=> 450,          ),        array(            "sku"=> "BL4438H",            "quantity"=> 1,            "description"=> "Super Hoop",            "price"=> 2392,          ),      ),    "tax"=> 251.42,    "total"=> 4443.52,    "comments"=> "Late afternoon is best. Backup contact is Nancy Billsmer @ 338-4338.",    );// 把该 invoice 转换生成 YAML 的表示法$yaml = yaml_emit($invoice);var_dump($yaml);// 把 YAML 转换成 PHP 变量$parsed = yaml_parse($yaml);// 来回转换，以检查两个结构是否相等效var_dump($parsed == $invoice);?>

以上例程的输出类似于：
