for循环和if语句每隔几次

Question

I have for loop from 1 to 6000 and I would like to execute a function every 100 times. I have only such an idea:

for($i=0;$i<=6000;$i++)
{
   if($i==100 && $i==200 ... $i==6000) do something;
}

How can I solve this problem differently?

Answer 1

From http://php.net/manual/en/language.operators.arithmetic.php

if ($i % 100 == 0) {
    // $i can be fully divided by 100
}
