Question

I need help creating PHP code to echo and run a function only 30% of the time.

Currently I have code below but it doesn’t seem to work.

if (mt_rand(1, 3) == 2)
{
    echo '';
    theFunctionIWantCalled();
}

Since you are using rand you can’t guarantee it will be called 30% of the time. Where you could instead use modulus which will effectively give you 1/3 of the time, not sure how important this is for you but…

$max = 27;

for($i = 1; $i < $max; $i++){
    if($i % 3 == 0){
        call_function_here();
    }
}
