how can i read values and stored it in php variable or use loop with above json string

Answer 1

You need to decode your json string by using json_decode() than you can use foreach() loop.

print_r(json_decode($jsonString,TRUE)); // will return response in an array

print_r(json_decode($jsonString)); // will return response in an object

And you can read the data as:

$decoded = json_decode($jsonString,TRUE);

foreach( $decoded as $key => $value ){
    // print values
    // print key
}

Answer 2

Try to use PHP built in function json_decode

http://www.php.net/manual/en/function.json-decode.php

Then access it like an array
