PHP Division By Zero?

[ShoeLace1291]

So, this is something that I've been wondering for a while now... say you have two variables that you need to divide to find a certain percentage and one happens to be zero... why does PHP feel the need to return a warning saying there was a division by zero?  why not just return the number zero since anything that's divided by zero always results in zero anyway?  Just a random thought.

That not true, division by zero is NOT equal to zero.  Just basic math.  Example, you have 3 / 0 != 0 because  0 x 0 != 3.  You get the point.  In which case, in PHP you can use the Error Suppression Operator, something like this.

 

$a = @(25/0);

 

Using the '@' Operator, the error is suppressed.

Or even better, you should do a check to see if your divisor is zero so you can handle the situation correctly.

Yea, these division by zeros are common questions asked in any programming job interviews.  Division by zero should always be handled no matter the language.

$number = 100;
if($me == 0)
$result = 0;
else
$result = $number / $me;
echo $result;
