Pass variable from one php file to another

Question

I am currently in file1.php and I want a variable from file1.php to pass to file2.php

How do I pass a variable from one php file to another?

I too want to go from file1.php to file2.php

I did following in file1.php:

session_start();
$_SESSION['akknum']="jkl";
header("Location: file2.php");

and did following in file2.php :

    <?php
    echo "abc";
    echo $_SESSION['akknum'];
    ?>

The file2.php is opening and abc is printing but no value of "jkl" is printing. What am I doing wrong?

is that case, depending on the way your visitors surf from file1.php to file2.php, you could use $_GET parameters in a link for example: <a href="file2.php?akkum=jkl">Link to file2.php</a> — GrafiCode

You need to add session_start(); in file2.php.

session_start();
echo "abc";
echo $_SESSION['akknum'];

Basic usage.

Won't super global variables reset when starting a new session?

You don't start a new session. If you send the same SID, you continue to use the same session data. But if you don't start the session, $_SESSION will be always an empty array.

If you want to use $_SESSION on a different file, you'll need to call session_start();

file1.php

<?php
session_start();
$_SESSION['akknum']="jkl";
header("Location: file2.php");
?>

file2.php

<?php
session_start();
echo $_SESSION['akknum'];
//jkl
?>
