I have some loop. How can i optimize this code that it would be executed each 12 items starting from 2nd item. I'm using hardcoded code for each of +12 item, but of course this is not a good solution :) I know it's easy to do and i was trying to do it with modulus operator, however it worked somehow incorrectly.
<?php if( ($counter == 2) || ($counter == 14) || ($counter == 26) || ($counter == 38) || ($counter == 50) || ($counter == 62) || ($counter == 74) || ($counter == 86) || ($counter == 98 .... ?>
Thanks for help!
Answer
Take a look at the Modulus operator (%):
<?php
if ( ( $counter - 2 ) % 12 == 0 ) {
//....
}
?>
Explanation
The Modulus operator (
$a % $b) is the remainder of$adivided by$b.
$counter - 2 - as you're starting with an offset of 2, remove that from $counter% 12 - will return the remainder of $counter - 2 divided by 12== 0 - if the above returns 0, you know that it is exactly divisible
