示例 #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:
string(631) "--- invoice: 34843 date: "2001-01-23" bill-to: given: Chris family: Dumars address: lines: |- 458 Walkman Dr. Suite #292 city: Royal Oak state: MI postal: 48046 ship-to: given: Chris family: Dumars address: lines: |- 458 Walkman Dr. Suite #292 city: Royal Oak state: MI postal: 48046 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.
