Question

Basically I have this code scenario:

if($_SESSION['player_1_pawn'][0]['currentHealth'] <=0 && 
   $_SESSION['player_1_pawn'][1]['currentHealth'] <=0 && 
   $_SESSION['player_1_pawn'][2]['currentHealth'] <=0 && 
   $_SESSION['player_1_pawn'][3]['currentHealth'] <=0 && 
   $_SESSION['player_1_pawn'][4]['currentHealth'] <=0) {
    //some code here
}

Is there any way to check or to loop through all of the indexes if all of
['player_1_pawn'][index]['currentHealth'] is smaller than 0,
instead of writing it one by one like I posted?

Answer 1

Just write a foreach construct that loops through all of the array elements you need to check:

$flag = true; // after the foreach, flag will be true if all pawns have <= 0 health
foreach ($_SESSION['player_1_pawn'] as $value)
{
  // for each pawn, check the current health
  if ($value['currentHealth'] > 0)
  {
    $flag = false; // one pawn has a positive current health
    break; // no need to check the rest, according to your code sample!
  }
}

if ($flag === true) // all pawns have 0 or negative health - run code!
{
  // some code here
}
