I believe it(i.e. your code) should be portable enough as it is... As regards a better way to achieve the same thing, i would do things differently (although the code is simple, it's also more readable...so bear with me)

function deleteFile($file_path){
    if(!is_file($file_path)){
        throw new Exception("The path does not seem to point to a valid file");
    }
    if(!file_exists($file_path)){
        throw new Exception("File not found!");
    }
    if(unlink($file_path)){
        return true;
    } else {
        throw new Exception("File deletion failed!");
    }
}

Of course you can always compress and improve on the code...hop this helps!
