How to catch url like /Username in php?

Question

PHP

On node this is done obviously, but how is it done in php?
Or an alternative.
Is it easier to do this in nginx?
How to direct nginx to only one index.php file and get "myUsername" from url /myUsername in $myVar variable?

Answer 1

Let's say /myUsername?a=1&b=2
$_SERVER['REQUEST_URI'] would be /myUsername?a=1&b=2
$_SERVER['DOCUMENT_URI'] would be /myUsername
