How to get the output of the current PHP?

Question

<?php
echo 'Hello';
echo 'World':

$e = // Get the output of the page.

echo $e; // 'HelloWorld' should be printed.
?>

I want to get all the output of the current page and print it as a variable.

For example, I printed 'Hello' and 'World' respectively. How can I get the content on the page?

It is possible to do this, but it is not particularly advisable. _Why_ do you want to do this? — Sammitch, Mar 03 '23 at 21:30

Use Output Buffering:

ob_start();
echo 'Hello';
echo 'World':

$e = ob_get_clean();

echo $e; // 'HelloWorld' should be printed.

More information can be found in the documentation: https://www.php.net/manual/en/ref.outcontrol.php

Worth noting that this assumes that output buffering is not already enabled, or that the buffer is empty beforehand. YMMV depending on buffering settings and application state. – Sammitch Mar 03 '23 at 21:31
