Why does the php code produce such a result?

PHP

function getRemainder($a, $b) {
return $a % $b;
}
echo getRemainder(50, 7);

% (Modulo) - Integer remainder of $a divided by $b.

Answer 1

Actually, 50% 7 = 7 and 1 in the remainder, which is what the function returned!

This is modulo division, that is, you get the remainder. Result 1.
