I have a this array scenario at first:
$_SESSION['player_1_pawn'][] = 'Warrior';
now when I want to add a third dimensional value like this:
$_SESSION['player_1_pawn'][0]['x'] = 1;
I get this output from
>$_SESSION['player_1_pawn'][0] : '1arrior'
My question is that, how to make that value stays intact as Warrior instead of 1arrior?
If the value is already a string, ['x'] accesses the first character of that string (yeah, don't ask ;)).
If you want to replace the whole thing with an array, do:
$_SESSION['player_1_pawn'][0] = array('x' => 1);
You cannot have $_SESSION['player_1_pawn'][0] be both the string "Warrior" and an array at the same time, so figure out which you want it to be. Probably:
$_SESSION['player_1_pawn'][0] = array('type' => 'Warrior', 'x' => 1);
Your problem is that $_SESSION['player_1_pawn'][0] is a scalar value equal to "Warrior". When you treat a scalar as an array, like you do with $_SESSION['player_1_pawn'][0]['x'] which evalueates $_SESSION['player_1_pawn'][0][0] or "W", you just change the first character in the string.
If you want to keep "Warrior" try this:
$_SESSION['player_1_pawn']=array('Warrior', 'x'=>1);
ETA:
given your requirements, the structure is this:
$_SESSION['player_1_pawn'] = array(
0 => array('Warrior', 'x'=>1),
1 => array('Wizard', 'x'=>7), //...
);
Which means you add like this:
$_SESSION['player_1_pawn'][]=array('Warrior', 'x'=>1);
