RewriteEngine On
RewriteRule ^([a-zA-Z0-9_-]+)$ profile.php?user=$1
RewriteRule ^([a-zA-Z0-9_-]+)/$ profile.php?user=$1
RewriteRule ^([a-zA-Z0-9_-]+)$ profile.php?user=$1
<?php
if(isset($_GET['user'])) {
echo $_GET['user'];
}
?>
or short version:
// Use outside php tags
<?=(isset($_GET['user']) ? $_GET['user'] : "guest")?>
// use inside php tags
echo (isset($_GET['user']) ? $_GET['user'] : "guest");
<?php echo $_GET['user']; ?>
anything that is in the url with this type: page.php?var1=x&var2=2
can be accessed via the global $_GET array because it's a variable sent by get protocol.
so the var1 and var2 in my example can be found in $_GET['var1'], $_GET['var2'].
and in your case if the page is website.com/profile.php?username=SomeUser
you can use $_GET['username'].
One last thing, NEVER under any circumstances, use the user input accessed through the global arrays directly in your code, evaluate it, clean it, escape it, what ever you need , then use it.
filter the data you get from the url
<?php
$user = filter_var($_GET['user'], FILTER_SANITIZE_STRING);
echo $user;
?>
RewriteRule ^([A-Za-z0-9_-]+)/?$ profile.php?user=$1 [L]
