• How to fix “Headers already sent” error in PHP 11 answers

I am writing a php-code which redirect me from localhost/login.php to localhost/index.page. I tried using the header('Location: index.php) method, but i keep receiving an error

Warning: Cannot modify header information - headers already sent by...

The error according to my search is due to a sort of output which is sent before the header() function. Unfortunately, after trying for hours, I could not figure out what is wrong with the code, so I am now looking for an alternative method.

Just another method, to redirect me from my "localhost/login.php" page back to my home page "localhost/index.php".

Instead of using PHP to do the redirect, use a META refresh that causes your browser to follow it:

<meta http-equiv="refresh" content="0; url=http://example.com/">

Information on META redirects: Meta_refresh
