I need to print something in a loop everytime a number is 10, 20, 30, 40...
It should only print once and then continue the loop and print again when the number is divisible by 10.
How can I achieve this?
for ($i = 0; $i < 100; $i++) {
if ($i % 10 == 0) echo $i."\n";
// do something
}
Generally the modulus operator (%) is what you need here. It calculates the remainder of a division. So: 7 % 5 = 2 and 18 % 5 = 3.
