yes i need to random a number, but i want to random a number every 15 mins.

is this possible?

add this at top

<?php

$_SESSION["code"]=rand(100,99999);

?>

 

Then in your html put

Enter the numbers: '<?php echo $_SESSION["code"];?>' 

 

that will do it

 

edit: on next page at top add

if {
($_SESSION["code"]==$_POST["code"]);
} else { 
echo "Wrong code";
}

Forgot add a form after that on html and use name="code" and have the form post so it works
