PHP DivisionByZeroError
Introduction
DivisionByZeroError class is a subclass of ArithmeticError class. This type of error occurs when division operation involves value of denominator as zero. This can also occur when a modulo operator (%) has 0 as second operator, and intdiv() function having second argument as 0.
DivisionByZeroError Example
In first example, we try to perform modulo division of 10 and 0 using % operator to induce DivisionByZeroError.
Example
<?php
try {
$a = 10;
$b = 0;
$result = $a%$b;
echo $result;
}
catch (DivisionByZeroError $e) {
echo $e->getMessage();
}
?>Output
This will produce following result −
Modulo by zero
If call to intdiv() function with 0 as second argument also raises DivisionByZeroError as follows
Example
<?php
try {
$a = 10;
$b = 0;
$result = intdiv($a,$b);
echo $result;
}
catch (DivisionByZeroError $e) {
echo $e->getMessage();
}
?>Output
This will produce following result −
Division by zero
Division operator (/) having 0 as denominator, however fails to raise error, instead raises warning because division results in PHP constant INF
Example
<?php
try {
$a = 10;
$b = 0;
$result = $a/$b;
echo $result;
}
catch (DivisionByZeroError $e) {
echo $e->getMessage();
}
?>Output
This will produce following result −
PHP Warning: Division by zero in C:\xampp\php\test.php on line 5 INF
