How to access JSON decoded array in PHP

$data = json_decode(...);
$firstId = $data[0]["id"];
$secondSeatNo = $data[1]["seat_no"];

Just like this :)

As you're passing true as the second parameter to json_decode, in the above example you can retrieve data doing something similar to:

$myArray = json_decode($data, true);
echo $myArray[0]['id']; // Fetches the first ID
echo $myArray[0]['c_name']; // Fetches the first c_name
// ...
echo $myArray[2]['id']; // Fetches the third ID
// etc..

If you do NOT pass true as the second parameter to json_decode it would instead return it as an object:

echo $myArray[0]->id;

$data = json_decode($json, true);
echo $data[0]["c_name"]; // "John"


$data = json_decode($json);
echo $data[0]->c_name;      // "John"
