Question

I have $var1, $var2, $var3 and $type. I want to check if $var1 and $var2 are empty when $type=1 but when $type=2 I want to check if $var1, $var2 and $var3 are empty.

I’ve tried with

 if(($type==1 AND empty($var) AND empty($var1)) OR ($type==2 AND empty($var1) AND empty($var2) AND empty($var3)))
 {//...}

but it doesn’t work in the second case when $type=2;
So how to get this done with one if statement?

Answer 1

Don’t use “if”, but take advantage of dropping through the cases in a switch

$result = TRUE;
switch ($type) {
    case 2:
        $result = $result && empty($var3);
    case 1:
        $result = $result && empty($var2);
        $result = $result && empty($var1);
        break;
    default:
        $result = FALSE;
}
