我目前有問題尋找一個特定的值，這是一個JSON文件中的new_user，我使用file_get_contents然後解碼它。無法解析PHP中的JSON以查找特定值？
這裏是我的代碼：
<html>
<head>
<link href="styles.css" rel="stylesheet" type="text/css" />
<title>PHP Bing</title>
</head>
<body><form method="post" action="<?php echo $PHP_SELF;?>">
Type in a search:<input type="text" id="searchText" name="searchText" value=""/>
<input type="submit" value="Search!" name="submit" id="searchButton" />
<?php
if (isset($_POST['submit'])) {
$request = 'https://devblogs.instavoice.com/vb?data={"cmd":"join_user","client_os_ver":"1511","client_app_ver":"vb.00.00.001","phone_num":"xxxxxxxxxxxxx","device_id":"xxxxxxxxxxxxx","phone_num_edited":"false","opr_info_edited":"false","sim_opr_mcc_mnc":"na","sim_country_iso":"in","api_ver":"2","app_secure_key":"xxxxxxxxxxx","client_os":"w","sim_serial_num":"xxxxxxxxxxxxxx"}';
$response = file_get_contents($request);
$jsonobj = json_decode($response);
foreach($json as $item)
{
if($item->new_user == "false")
{
echo "ssdasdSA";
}
else {
echo "Sdasds";
}
}
} ?>
</form>
</body>
</html>
這裏是我試圖尋找new_user的JSON輸出：

你不變量'$ json'，這是'$ jsonobj'。 – Barmar
