PHP 7 The intdiv() function is newly added. intdiv represents integer division, which means rounding the division result. This function returns the integer quotient of division by the given dividend and divisor. This function internally removes the remainder of the dividend, making it divisible by the dividend and returns the quotient after division.

Syntax:

int intdiv($dividend, $divisor)
Copy after login

Parameters:

The function receives two parameters:

$dividend: This signed integer parameter represents the number to divide by.

$divisor: This signed integer argument refers to the number used as the divisor.

Return type:

This function returns the calculated quotient.

Exception/Error:

This function will throw an exception in the following situations:

If we pass the divisor as 0, then the function will raise DivisionByZeroError abnormal.

If we take PHP_INT_MIN as the dividend and -1 as the divisor, then an arithmetic error exception will be thrown.

PHP intdiv code usage example:

<?php 
  
$dividend = 19; 
$divisor = 3;  
  
echo intdiv($dividend, $divisor);
Copy after login

Output:

6
Copy after login

Looking at so far many people may think that this function is equivalent to :

floor($dividend/$divisor)
Copy after login

But there is a difference between the two, the example is as follows:

<?php 
  
$dividend = -19; 
$divisor = 3;  
  
echo intdiv($dividend, $divisor) ."\n".  
             floor($dividend/ $divisor); 
  
?>
Copy after login

Output:

-6
-7
Copy after login

Note:

intdiv() function returns the quotient of integer division.

This function may throw exceptions, so developers must handle edge cases.

This function is not equal to the floor function applied to floating point division or '/'.
