PHP routing help needed

Question

My .htaccess file is like this:

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^ index.php [L]

And my index.php:

echo '<pre>';
print_r(explode('/', $_SERVER['REQUEST_URI']));
echo '</pre>';

When I go to example.com/test/one/two, it gives me back:

Array
(
    [0] => 
    [1] => test
    [2] => one
    [3] => two
)

Why is there a 0?

Because your $_SERVER['REQUEST_URI'] is /test/one/two.

To get rid of that you could remove first slash from $_SERVER['REQUEST_URI']:

substr($_SERVER['REQUEST_URI'], 1);

But why in the array is there a 0. I know arrays starts with a 0. Why is 'test' not the beginning of the array?

Because there is an empty string in front of the first slash

explode function splits string on boundary formed by delimiter parameter. So when you have your delimiter as first character in string it puts an empty string into a resulting array.
