This is a bootstrap thumbnail. I need PHP to count 4 users in one row and then star ta new row of users. How can I do this?

Answer 1

You can use the modulus to find out if the current thumbnail is the last in a row of four:

$is_last_of_four = $x % 4 === 0;

You can use this result to insert additional markup that ends the current row and starts a new one.
