如何在用户每次登录时调用脚本（或者每当会话处于活动状态时）

Question

I am trying run a script called random_post_generator.php which should execute every time a user is logged in.

I am using this approach as an alternative to cron.

Here is how my session is currently created:

<?php
ob_start();
session_start();
if (!isset($_SESSION["user_login"])) {
    header("Location: index.php");
} else {
    $username = $_SESSION["user_login"];
}
?>

But how do I say - "if session is active, then run this script"?

Answer 1

<?php
ob_start();
session_start();
if (!isset($_SESSION["user_login"])) {
    header("Location: index.php");
} else {
    $username = $_SESSION["user_login"];
    include 'random_post_generator.php';
}
?>

or you can use require 'random_post_generator.php'
