intdiv()¶
intdiv() is a PHP native function, that computes the integer division between two integer. The integer division of a by b express the number a as a function of b, such as a = k * b + c.
intdiv() returns the k value, which is the quotient. It is an integer. The remainder, c is accessible with the modulo operator %. There is no operator equivalent to intdiv().
The integer division is a special case of the division, which works on decimal numbers.
<?php
$a = 15;
$b = 6;
$k = intdiv($a, $b); // 2
$c = $a % $b; // 3
echo $k * $b + $c;
?>
