php - Json array encode and decode the same -

i encode array json format using code below :

$arrayname[] = array('user_role_id' => 1, 'user_id' => 1); $arrayname[] = array('user_role_id' => 2, 'user_id' => 2);  $jos = json_encode(array_values($arrayname)); 

the output is

[{"user_role_id":1,"user_id":1},{"user_role_id":2,"user_id":2}] 

and sent browser.

then after steps browser returns same array.

but when try decode

$return = json_decode($jos,true); 

i receive error : array string conversion.

browser didnt array. returns supply.

code flow :

<?php  if(isset($_get['array'])) {     $arrayname[] = array('user_role_id' => 1, 'user_id' => 1);     $arrayname[] = array('user_role_id' => 2, 'user_id' => 2);     header('content-type: application/json');     echo $jos = json_encode($arrayname); } else {     if(isset($_post['jos']))     {         $jos = $_post['jos'];          echo $new_jos = json_decode($jos,true);     } } 

can please me?

what might wrong?

the problem line:

echo $new_jos = json_decode($jos,true); 

so convert json string array(that works!) , echo - throws error.

just use

$new_jos = json_decode($jos,true);
