How can i Iterate through data returned in Ajax success?

Question

How can I iterate to get id value? This is my array:

[{"email_id":"gayatri.dsf@detedu.org","Id":"216"}]

tried

<?php
    foreach($faculty as $value)
    {
       echo $value['Id'];
    }
?>

Gives an error

Use of undefined constant Id - assumed Id

This is a json which is basically a string, to be more precise the given json contains a list (currently 1 element):

[{"email_id":"gayatri.dsf@detedu.org","Id":"216"}]

You need to convert it to an array first:

$jsonValues = json_decode($json, true); //here you will have an array of users (1 now)
foreach($jsonValues as $faculty) //for each user do something
{
    echo $faculty['Id'];
}
