Hi DaniWeb users.
I am creating a mp3 shop cart script, and I need a function to create a unique id of multiple items in the cart.
for example in cart are these id's: 1,6,21,5
base64 would make this: MSw2LDIxLDU=
I need it only alphanumeric as it is ment to be sent from a sms!
So when the user sents the sms, my server needs to "decode" it and get the cart items user 'purchased' from with a sms!
