如何在PHP中访问JSON元素，如数组对象？

问题描述 投票：2回答：2

从触发this Webhook，我收到一个order object，当我在电子邮件中输出时，它看起来像这样：

数组{ “ID”：1154， “PARENT_ID”：0， “状态”： “待定”， “货币”： “EUR”， “版本”： “3.2.3”， “prices_include_tax”：真实的， “DATE_CREATED”： {“date”：“2017-12-15 15：58：42.000000”，“timezone_type”：1，“timezone”：“+ 00:00”}，“date_modified”：{“date”：“2017-12- 15 15：58：42.000000“，”timezone_type“：1，”timezone“：”+ 00:00“}，”discount_total“：”0“，”discount_tax“：”0“，”shipping_total“：”0“， “shipping_tax”： “0”， “cart_tax”： “0”， “总”： “6.50”， “total_tax”： “0”， “CUSTOMER_ID”：0 “order_key”： “wc_order_5a33f1321ba43”， “计费”： {“first_name”：“Peter”，“last_name”：“Parker”，“company”：“”，“address_1”：“Baker Str。”，“address_2”：“2”，“city”：“London”， “状态”： “”， “邮政编码”： “50668”， “国”： “DE”， “电子邮件”： “[email protected]”， “手机”： “01627423”}， “发货”：{” first_name“：”Peter“，”last_name“：”Parker“，”company“：”“，”address_1“：”Baker Str。“，”address_2“：”2“，”city“：”London“，”state“ “：”“，”邮政编码“：”50668“，”country“：”DE“}，”payment_method“：”cod“，”payment_method_title“：”Bei Abholung“，”transaction _id“：”“，”customer_ip_address“ ：” ... “” customer_user_agent “：” Mozilla浏览器/5.0（macintosh; intel mac os x 10_13_2）applewebkit / 537.36（khtml，like gecko）chrome / blabla safari / 537.36“，”created_via“：”checkout“，”customer_note“：”“，”date_completed“：null，”date_paid“：null， “cart_hash”： “be97db19eba58864b9166961ce22a706”， “号码”： “1154”， “meta_data”：[{ “ID”：4731， “钥匙”： “_ billing_title”， “值”： “1”}，{ “ID”： 4732， “键”： “_ shipping_title”， “值”： “1”}]， “line_items”：{ “18”：{}}， “tax_lines”：[]， “shipping_lines”：{ “19”：{ }}， “fee_lines”：[]， “coupon_lines”：[]}

能否请您指出访问此JSON元素的可能性，以便我可以构建来自$order对象的某些部分的消息？我尝试了$data = json_decode($order)和$data->date_created结合但是当我倾倒最后一部分时我没有给我任何东西。

它是json，除了开头的Array部分（假设你尝试访问date_created）：

你可以像往常一样使用json_decode()，但date_created也是一个数组，所以你还需要选择你想要的项目。

$data = json_decode($order, true);

echo $data['date_created']['date']; // 2017-12-15 15:58:42.000000

因此，如果您想要客户名称，例如：

echo $data['billing']['first_name'].' '.$data['billing']['last_name'];

通过print_r($data)'ing它你可以看到它的结构。

Array

    [id] => 1154

        (
        )

    [coupon_lines] => Array
        (
        )

)

如果您想要一个简单的输出，您可以使用递归函数遍历数组，这将生成您的电子邮件。

echo '<h2>Order Details</h2>'.PHP_EOL;
echo order_details(json_decode($json, true));

function order_details($items, $str = null) {   
    foreach ($items as $key => $item) {
        if (is_array($item)) {
            $str .= PHP_EOL.'<h3>'.ucwords(str_replace('_', ' ', $key)).'</h3>'.PHP_EOL;
            $str .= order_details($item, $str);
        } else {
            $str .= '<b>'.ucwords(str_replace('_', ' ', $key)).'</b>: '.$item.'</br>'.PHP_EOL;
        }
    }
    return $str;
}

其输出如下：https://3v4l.org/l9BS4

当你使用

$data = json_decode($order);

它将创建一个对象，将此对象转换为您只需传递参数的关联数组

$data = json_decode($order, true);
