Re: Anyway of knowing whether a integer is odd or even

Is if ($theInt & 1) really that much harder to read than if ($theInt % 2 > 0) ? And why wouldn't you want to get the most performance out of your code, regardless of the language, scripting or otherwise? Especially when it's a one or two character switch that makes the difference? I doubt that PHP should be classified as a scripting language any more than Perl is. Scripting languages are usually used to glue different applications together, like a shell script that uses awk and sed or whatever. PHP can be used to build applications, so it's more than a scripting language. Interpreted language is more like it.
