Php Custom Division Function

Question

I'm thinking about writing a simple function to handle all my division for my web application. The main reason is to catch division by 0 errors. I'm thinking I'll just return 0 when division by 0 is attempted.

Am I completely thinking wrong here?

The web application is very extensive and currently used by 5 different businesses. It records and processes over 10,000 different records every day. So saying stop dividing by zero is simply not a solution.

Try something like this:

function division($dividend, $divisor) {
    if ($divisor == 0) {
        //change this return value to whatever fits your code 
        return 0;
    } else {
        return $dividend / $divisor;
    }
}

Usage:

echo division(4, 2);     // 2
echo division(9, (5-1)); // 2.25
echo division(1, 0);     // 0

You could also throw an Exception if the divisor equals zero or return false, for example, and treat the error in whatever way you need.
