Question

I’m not so sure how to write this: I want to generate a random number from 0 to 2, then write an if statement which executes specific code only 33% of the time.

This is what I tried to do:

if (rand(0, 3)=="2") { echo "Success" };

Answer 1

The two arguments represent the minimum and maximum random values. If you want a 1-in-3 chance, you should only allow 3 possibilities. Going from minimum 0 to maximum 3 allows 4 possible values (0,1,2,3), so that won’t quite do what you want. Also, mt_rand() is a better function to use than rand().

So it’d be:

if (mt_rand(1, 3) == 2)
    echo "Success";
