Question

Hey I have dynamic image begin created with imagecreate(), and I have random values being produced, and I want to pass that random number, to a variable, and use that variable inside the page where Im using the image source.

The image is on random.php, and Im using <img src="random.php" /> on page index.php if that matters, and I want to pass from random.php (the image), to index.php. I already tried sessions and cookies but when I refresh, its always 1 step behind what the image is producing…

Im using a for loop to echo random numbers, I need to pass those numbers to a variable. Basicly how do I get numbers outside an image, in real time, not 1 step back.

What about using a temporary session variable?

On your first page,

<?php
    session_start();
    $_SESSION['mykey'] = 'myrandomval';
    session_write_close(); // Helpful if you're using a header redirect
?>

and on the second page

<?php

    session_start();
    $value = $_SESSION['mykey'];

?>
