How to deduct time in php?

I wrote this

<?php
session_start();

if(!isset($_SESSION['now'])){
$_SESSION['now'] = time();
}

if(time() > ($_SESSION['now'] + 300)){
echo "15 minutes have passed";
} else {
echo "waiting";
}

?>

What I want to do is, let the user wait for 15 minutes before he/she can view the page. Is the code correct?

The time() function returns the number of seconds since the Epoch. 15 minutes is equal to 900 seconds, not 300. Other than that the code is correct.

Yes the code is correct, you can try it simply by having a smaller time constraint.

if(time() => ($_SESSION['now'] + 900)){

Just to be extra sure.

Try this to see what your variables are printing out.

<?php
session_start();

if(!isset($_SESSION['now'])){
$_SESSION['now'] = time();
}

if(time() > ($_SESSION['now'] + 10)){
    echo date("d.m.Y H:i", time())."<br />";
    echo date("d.m.Y H:i", $_SESSION['now'])."<br />";
    echo "15 minutes have passed";
} else {
    echo date("d.m.Y H:i", time())."<br />";
    echo date("d.m.Y H:i", $_SESSION['now'])."<br />";
    echo "waiting";
}

?>
