make switch use === comparison not == comparison In PHP

Question

Is there anyway to make it so that the following code still uses a switch and returns b not a? Thanks!

$var = 0;
switch($var) {
            


        

Answer 1

Switch statement in php does loose comparisons only (==) see http://www.php.net/manual/en/control-structures.switch.php

Use if/elseif/else if you need strict comparisons.

Answer 2

Presumably you are switching on the variable and expecting integers. Why not simply check the integer status of the variable beforehand using is_int($val) ?

Answer 3

Extrapolating from your example code, I guess you have a bunch of regular cases and one special case (here, null).

The simplest I can figure out is to handle this case before the switch:

if ($value === null) {
    return 'null';
}

switch ($value) {
    case 0:
        return 'zero';
    case 1:
        return 'one';
    case 2:
        return 'two';
}

Maybe also add a comment to remember null would unexpectedly match the 0 case (also the contrary, 0 would match a null case).
