This is what i receive and i tried to access single value with these commands + here is my php code.

<?php


$data = file_get_contents("php://input");
$arr = json_decode($data, true);



print_r($arr);// This commands return above string in same format. 

?>

Commands i tried.

$title = $arr[0]['title'];// No success Eror = Undefined index
$title = $arr(0)// of course not success.
$title = $arr[0][1];

Is there any way to access this array.

Answer 1

Your array keys appear to have a trailing space, so change to:

$title = $arr[0]['title '];
