Question

Hello i’m having trouble with making like a simple waiting time between 2 php requests like…
i have this code (for example) :

readfile($link);

the visitor request this php code to download a file … but within 10 seconds he requests another one … i want to make a limit for the time like if he requested once he has to waiting from the first download to the allowance to the second request (download) 30 seconds … any idea of how could this be done ? in php … thank you in advance 🙂

edit :
i tried with the help of the post below but did not work

if (!isset($_SESSION['last_download'])) $_SESSION['last_download'] = 0; {
if (time() - $_SESSION['last_download'] > 10){
    $_SESSION['last_download'] = time();
    echo $_SESSION['last_download'];
    }else {echo"".time() - $_SESSION['last_download']."";}}

but its not saving the session … any help ?

Answer 1

Just save last download time into a session

<?php
if (!isset($_SESSION['last_download'])) $_SESSION['last_download'] = 2; //time in past
if ($_SESSION['last_download'] && time() - $_SESSION['last_download'] > 10){
    $_SESSION['last_download'] = time();
    //allow download
}
