Division by zero

Anon

Is it possible to ignore the division by zero warning on a page. Basicly I know its there and its ok to be there but I dont want that particular error printing on the screen.
Can I somehow make it not print that?

Sure, change your program to account for it.

Division by zero is not allowed, so your program should never try to do it.

a simple IF statement solves it all:

if ($iMyNumber != 0)
{
$iOurcome = 10/$iMyNumber;
}
else
{
// do something else.
};

Now people are probably going to tell you about using the @ sign or stepping down the error-reporting, but those are not solutions, they are workarounds for bad programming.

Error suppression

By putting the @ in front of a function an error can be supressed that would be printed by PHP. The common error the Wrox team points out is the division by zero that can occur. I usually make code which will compare the value of the code rather than suppress the error. Let's take the following example below:

$number = 0;
$average = 3 / $number;
print($average);

Line 3 above will result in a division by zero error. The error will not be shown if you put a @ in front of the third line like this:

@print($average);

I would probably write the code above like this, however:

$number = 0;
if ($number > 0) { $average = 3 / $number; }
print($average);

I guess rather than suppressing error message I'd rather write code that makes sure there is no possibility of an error, but the error suppression tip is useful.
