Re: [PHP] Displaying full array contents

[debbie_dyer]

You could use recursion example:-

  function printArray($arr) {
    for ($i =0; $i < count($arr); $i++) {
      if (!is_array($arr[$i])) {
        echo $arr[$i];
      }
      else {
        printArray($arr[$i]);
      }
    }
  }
 
$arr = array("Orange", "Peach", "Apple");
$arr2 = array("Banana", $arr, "Pear");
$arr3 = array($arr, $arr2);

printArray($arr3);
