[PHP] How to remove a variable from an array

[Jake McHenry]

I have an array variable that is set, then put into a session
variable. All is good so far, but how can I remove a specific variable
from the array?

I have tried basically copying and pasting this, and adding a foreach
loop. Inside this foreach loop, the array is split apart and I tried
using unnset, but I couldn't get it to work, so I deleted the code.

Here is how I built the array:

  if ($_POST['4_Add'] != "")
  {
    if (($_POST['Frequent_Guest_Program'] != "") &&
($_POST['Frequent_Guest_Number'] != ""))
    {
      $array = array();
      $new =
"{$_POST['Frequent_Guest_Program']},{$_POST['Frequent_Guest_Number']}"
;
      $old = $_SESSION['Frequent_Guest'];
      $array = array_merge($old, $new);
      $_SESSION['Frequent_Guest'] = $array;
    }
    header("Location: profile4.php");
  }
