How can I loop through a JSON Object in PHP?

Question

I have a variable $arr in PHP. It has the following data inside it.

This is my PHP Code.

    $data = array(
        'Request' => 'StockStatus',
        'merchant_id' => 'shipm8',
        'hash' => '09335f393d4155d9334ed61385712999'
        );

    $url = 'https://ship2you.com/ship2you/';

    $ch = curl_init($url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
    curl_setopt($ch, CURLOPT_PORT, 443);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
    $result = curl_exec($ch);
    curl_close($ch);

    $arr = json_decode($result, true);

    foreach ($arr as $value) {
        echo $value['packagename'];
    }

I want to loop through it. How can I achieve it? I tried using foreach but it gives me error. Thanks in advance.

Come on, post the code! Now you added a snippet, but still not the foreach you mentioned... — GolezTrol

You have to decode your CURL output string twice:-

$arr = json_decode(json_decode($result, true),true);

foreach ($arr as $value) {
    echo "<pre/>";print_r($value['packagename']);
}

Note:- @Xatenev mentioned the correct thing:-

The json has escaped quotes. When a json with escaped quotes is passed to json_decode() it only removes all the escaped sequences. When calling json_decode() again, it decodes it correctly

Why do i have to do it twice?

Death-is-the-real-truth Over a year ago

@AliZia It seems that double-encoded or you can say nested encoded string comes from CURL request

I wish my API Provider would have mentioned it. Thankyou so much.

json_decode($json, true);

If the second parameter is true, it will return array. In case it is not what you are looking for, please show the code you have.

$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_PORT, 443);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
$result = curl_exec($ch);
curl_close($ch);

$arr = json_decode($result);



foreach ($arr as $arr_item) {
   echo $arr_item->user_id;
}
