How to determine every Nth iteration of a loop with PHP?

To determine every Nth iteration of a loop with PHP, we can check the index variable value with the modulo operator.

For instance, we write

$x = 3;

for ($i = 0; $i < 10; $i++) {
    if ($i % $x == 0) {
        // ...
    }
}

to check if loop variable $i is evenly divisible by $x with

$i % $x == 0

Conclusion

To determine every Nth iteration of a loop with PHP, we can check the index variable value with the modulo operator.
