  if (isset($_POST["chedit"]))
       {
          $text = $_POST["text"];
          $mumu = $_POST["edit"];
            $_SESSION["text"] = $text;

            $_SESSION["mumu"] = $mumu;

            $text = $_SESSION["text"];

            $mumu = $_SESSION["mumu"];

            echo $text;

            echo $mumu;

            }

every thing is working fine but if i try to reopen this page i got my recent output lost can any fixed this? Big thanks

This way $_POST['text] and $_POST['edit'] will be stored in $_SESSION['text'] and $_SESSION['mumu'] and always printed:

<?php  
session_start();
if (isset($_POST["chedit"]))
{
    $text = $_POST["text"];
    $mumu = $_POST["edit"];
    $_SESSION["text"] = $text;
    $_SESSION["mumu"] = $mumu;
}
if (isset($_SESSION["text"]) && isset($_SESSION["mumu"]))
{
    echo '<p>' . $_SESSION["text"];
    echo '<p>' . $_SESSION["mumu"];
}
?>

But of course you can use that variables however you want. They will be stored as long as you don't close the navigator.
