PHP Code: [ Select ]
<?php
// $interval needs to be in seconds
function cronjob($interval, $ses_name = 'T_CRONJOB')
{
    if(isset($_SESSION[$ses_name]))
    {
        $time = time() - $_SESSION[$ses_name];
        if($time > $interval)
        {
            return true;
        }
    }
   
    $_SESSION[$ses_name] = time();
    return false;
}
 
if(cronjob(60) == true)
{
    // do your code here
}
?>
  1. <?php
  2. // $interval needs to be in seconds
  3. function cronjob($interval, $ses_name = 'T_CRONJOB')
  4. {
  5.     if(isset($_SESSION[$ses_name]))
