You can access the object property by using the ->

您可以使用 - >访问对象属性

<?php
    $jsonObject = json_decode($_GET["UserDetails"]);
    echo $jsonObject->Email; // will print joissumanh@gmail.com
?>

Once you use json_decode() function, then the assigned variable becomes PHP stdClass, which can be access as below.

一旦你使用了json_decode（）函数，那么赋值的变量就变成了PHP stdClass，可以如下访问。

<?php

$jsonAsString = '{"Email": "username@domainname.tld"}';

$jsonObj = json_decode($jsonAsString);

// Now $jsonObj is a stdClass Object which can be accessed as below

echo $jsonObj -> Email;

?>
