以下是推送到我的webhook的数组数据示例
我对PHP不太了解并知道我正在调用返回的电子邮件错误，我如何从该子数组中获取电子邮件地址？我想也许可能超过1个电子邮件的阵列父母，但我想现在很好只是抓住电子邮件结果，如果存在。
PHP：
//Get and decode JSON
$str = file_get_contents("php://input");
$json = json_decode($str, true);
// debugging
print_r($json);
$tracking_number = $json['msg']['tracking_number'];
$tracking_status = $json['msg']['tag'];
$tracking_email = $json['msg']['emails'];
$customer_name = $json['msg']['customer_name'];
$userarr = Array(
Array(
'tracking_number'=>$tracking_number,
'tracking_status'=>$tracking_status,
'tracking_email'=>$tracking_email,
'customer_name'=>$customer_name
)
);
// debugging
print_r($userarr);
//Update to the latest shipment status
//update_post_meta( $shiporderid, '_shipment_status', $shipmentstatus );
//Check if shipping status = InTransit, set order status to complete
//if($shipmentstatus == 'InTransit'):
// $order = wc_get_order( $shiporderid );
// $order->update_status( 'completed' );
//endif;
$m = new MailSender;
$m->sendMail($userarr, 'StatusUpdate');

您只需要进入$userarr对象内的每个键。请注意，james@是emails中的第一个元素，它本身就是一个数组，因此最后一步需要[0]访问第一个索引，或者需要emails键上的循环。
为此，您可以使用方括号表示法：
$userarr["event"]["msg"]["emails"][0] // [email protected]
或箭头符号：
$userarr->event->msg->emails[0] // [email protected]
希望这可以帮助！ :)
