999 Roll

This PHP script simulates 100,000 lottery number draws and counts the results. It uses hashes and random number generation to simulate lottery numbers between 0-9999. The script outputs the counts of numbers that match certain prize tiers out of the 100,000 draws. Functions are used to generate random seeds, strings, and numbers within a range.
