I'm doing a question game in PHP, the user will have 15 seconds to answer each question, how to prevent the user from changing the timer via inspect element and add seconds?
Just adding details, it is impractical to let the user change the time from 15 to 50 seconds for example and check if the time beats via PHP because I want to implement the game so that 2 users play simultaneously, then both would have 15 seconds and would advance the questions together.
