You could use cookies but you will need Javascript to achieve it because "cookies" are client side, not the server side. You will have to learn Javascript first. To incorporate with PHP, simply echo the script out to the HTML page.

setcookie() is used to write a cookie in PHP. However, you cannot retrieve the info from the cookie you just set until another page has been accessed.
We read a cookie from the $_COOKIE superglobal var.

JS can read/write the same cookies. You dont have to use JS. You don't have to use PHP. It depends on your needs.

Here's an example:

$hours = 1;
$cookie = [
    "name" => "myCookie",
    "value" => 123,
    "expire" => time()+(3600*$hours) // Set the cookie expiry to 1 hour (3600 seconds) * $hours
];
setcookie($cookie['name'], $cookie['value'], $cookie['expire']);

// Check if it was created
if (isset($_COOKIE[$cookie['name']))
{
    echo $cookie['name'] . " is set.";
}

// Get it from another script
$user_id = $_COOKIE['myCookie']; // $user_id is now 123 (or whatever your cookie's value is)

code untested but should be valid; wrote it within the DaniWeb editor. if you have any questions just ask me

You're missing a ] in the conditional statement in line 10
This script will return an error due to cookie not set on line 16. It should work on page reload though.

@diafol — good spotting!
Also, I know that line 16 won't work instantly if they put it there. Hence the "// Get it from another script". ;D
