Hi Folks,

I do see some websites with extensions such as the one below where extra numbers and letters possibly on base 32 have been added to the URL.

Code:
http://www.mywebsite.com/index.php?lh=566057805f1cc3cc5885dde4cc663f32
If anyone has had experience in creating something like this, could they tell me how to achieve that with PHP, please?

Thanks,
Menre
