[SOLVED] Percent sign

[frost]

In the following:

 

if($var%2)

 

Does the % stand for "divisible by"?

 

I ask because I tried if($var%3) and got some wacky stuff...

 

Thanks.

It is the modulus operator. In your first example, it will return the remainder of $var divided by 2.

[effigy]

In other words, if ($var is an odd number).

Ah, that makes sense.

 

So if I wanted to see if $var was divisible by 3 how would I do that?

If you want to see if something is divisible by three use the following:

if($var%3 == 0) {

}
