PHP URL查询

Question

How exactly would I get the URL with PHP so I could do this:

profile.php?username=Blah

How would I get the 'Blah' from the username= part by using PHP?

Answer 1

In PHP there are global variables that hold parameters passed on the url or by posting a form. Some of this variables are $_GET, $_POST, $_REQUEST, $_FILES.

<?php
$username = $_GET['username']
echo $username;
