I got curious if one could construct emoji URLs…
.htaccess
RewriteEngine On
RewriteRule (.+) index.php?request=$1 [L,QSA]
index.php
$requestArray = explode("/", $_GET['request']);
echo “Welcome to my page about “;
if(urlencode($requestArray[0]) == ‘%F0%9F%90%A8’) echo ‘koalas’;
echo ‘ eating ‘;
if(urlencode($requestArray[1]) == ‘%F0%9F%8D%94’) echo “burgers!\n”;
