Problems with sessions

I have extracted these codes from a complete script of mine, the string $stat will only be "Printed" after the $stat is set and the page is refreshed .. How can we recode the script so that the $stat gets displayed without a need to refresh the page.

<?php
 
$stat=$_SESSION['stat'];
if ( ( $_POST["code"] == $rand ) && ( $_POST["message"] != "" ) ) {
$_SESSION['stat'] ="Message Submitted";
 }
 
elseif (( $_POST["message"] == "" ) && ( $stat != "" )) { $_SESSION['stat'] ="No message entered"; }
elseif (( $_POST["code"] != $rand ) && ( $stat != "" )) { $_SESSION['stat'] ="Wrong verification code"; }
 
echo $stat;
?>

Code (markup):

Again, a summary of the problem:
1)Script sets a value for $stat after checking through an IF condition.
2)$stat does not gets displayed because the string for $stat was set AFTER the page is loaded.
3)$stat gets displayed after a page refresh because at that point $stat is set ( previous $stat value, not the new one )

 

First thing - check if your $rand works ..
Second thing - you don't need to reload the page - PHP works as 1,2,3 .. 1 will add a value, 2 will print it out

 

It works, I have removed the other statements which were present within the IF condition box but they do get executed along with the setting up for the $stat string. $stat string does still not gets displayed however.
