从对象获取字符串

Question

如何从PHP中获取此对象的电子邮件变量？

$data = $_POST["data"];

$data的内容：

Object {email: "peter.m@gmail.com"} 

Answer 1

也许这是一个json字符串？ 尝试：

$data = json_decode($data);
$email = $data->email;

Answer 2

这应该有效＆＃34;

$email_string = $data->email;  //should work

//    or

$email_string = $data['email'];   //might also work
