I'm fairly new to PHP programming and I'm currently working on a project that involves credit card validation. I've read about the Luhn algorithm and I think it's the best way to validate credit card numbers. However, I'm having trouble implementing it in PHP.
I was wondering if anyone here has a sample PHP program that demonstrates how to validate a credit card number using the Luhn algorithm? It would be a huge help if someone could provide me with a working code example or guide me towards a tutorial or documentation that explains this process.
I really appreciate any assistance or advice you can provide. Thank you in advance!
