Re: [PHP] Displaying full array contents

[debbie_dyer]

Use a static variable in the function? A static var retains its value
between function calls

function printArray($arr) {
    static $depth = 0;
    for ($i =0; $i < count($arr); $i++) {
      if (!is_array($arr[$i])) {
        echo "$depth $arr[$i]";
      }
      else {
        $depth++;
        printArray($arr[$i]);
        $depth--;
      }
    }
  }

  $arr = array("Orange", "Peach", "Apple");
  $arr2 = array("Banana", $arr, "Pear");
  $arr3 = array($arr, $arr2);

  printArray($arr3);
