PHP Lottery Script Simulation

This document contains PHP code that simulates running a lottery game 100,000 times to calculate the expected number of wins in different prize tiers. It initializes variables to track the counts of jackpot wins, 10k prize wins, and wins in various number ranges. It then runs a loop 100,000 times, generating random numbers, checking the ranges, and incrementing the count variables. After the loop, it displays the final count values.
