Answer 1

if(!isset($_COOKIE['lg'])) {
    setcookie('lg', rand(1,10000), time() + (86400 * 30), "/"); // 86400 = 1 day
}
echo $_COOKIE['lg'];

You can check if it is not set then set it.

Answer 2

<?php
define('COOKIE_KEY', 'COOKIE_KEY');
if (!array_key_exists(COOKIE_KEY, $_COOKIE)) {
    setcookie(COOKIE_KEY, mt_rand(1, 10), time()+3600);    
}

Answer 3

Your set cookie code is incorrect and the cookie time is only 1 second

change your code as follows...

<?php 
//cookie_start();
global $random; 
$random= rand(0, 9999999); 
if(!isset($_COOKIE['user_cookie'])) {
    setcookie('user_cookie',$random, time() + (86400), "/");//86400 = 1 day
}
else {
    echo "Cookie '" . $_COOKIE['user_cookie'] . "' is set!<br>"; 
}
exit();  
?>
