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");
}
