can we know from which page the user visited this page in php?

Is it possible in PHP to know which page a user came to a particular page from?

For example, the first page is index.php and the second page is index2.php.

index.php

index2.php

Now the user goes to index.php from index2.php using a hyperlink which is on index2.php.

index.php

index2.php

index2.php

Now I want to store the link in a database, for the page the user came to index.php from, in this case index2.php.

index.php

index2.php

If it's on your own site you might as well use the session, HTTP_REFERER is prone to spam or very likely simply not set, you can't trust it.

HTTP_REFERER

Maybe do something like:

<?php
session_start();

if (!isset($_SESSION['last_page']))
// first visit (landing)
else
// not first page


// insert into db

// set tracking for next page
$_SESSION['last_page'] = [
'page' => $_SERVER['REQUEST_URI'],
'time' => time() // know how long user was on the last page
];


Place it somewhere its hit on each page.

You can access the last page URL (which in this case will be the origin) using $_SERVER['HTTP_REFERER'].

$_SERVER['HTTP_REFERER']

If you only want to track sites that are from you, like index.php and index2.php then you should use a session and set the value on each page, its more precise than the $_SERVER['HTTP_REFERER'] variable.

index.php

index2.php

$_SERVER['HTTP_REFERER']

$_SERVER['HTTP_REFERER'] can easily be spoofed be the user.

$_SERVER['HTTP_REFERER']

You can use the global variable $_SERVER, it should tell you where the user came from.
You can use it like this in your index.php:

$_SERVER

echo $_SERVER["HTTP_REFERER"];
