switch statement with two variables at a time

Question

Could someone suggest the best way to have the following switch statement? I don\'t know that it\'s possible to compare two values at once, but this would be ideal:

Answer 1

var $var1 = "something";
var $var2 = "something_else";
switch($var1.$var2) {
case "somethingsomething_else":
    ...
    break;
case "something...":
    break;
case "......":
    break;
}

Answer 2

Found at http://www.siteduzero.com/forum/sujet/switch-a-plusieurs-variables-75351

<?php
$var1 = "variable1";
$var2 = "variable2";
$tableau = array($var1, $var2);

switch ($tableau){
    case array("variable1", "variable2"):
        echo "Le tableau correspond !";
    break;

    case array(NULL, NULL):
        echo "Le tableau ne correspond pas.";
    break; 
}
?>

Answer 3

You can change the order of the comparison, but this is still not ideal.

    switch(true)
    {
      case ($color == 'blue' and $size == 'small'):
        echo "blue and small";
        break;
      case ($color == 'red' and $size == 'large'):
        echo "red and large";
        break;
      default:
        echo 'nothing';
        break;
    }

Answer 4

Your other option (though not pretty) is to nest the switch statements:

switch($color){
    case "blue":
        switch($size):
            case "small":
            //do something
            break;
    break;
}

Answer 5

Doesn't work. You could hack around it with some string concatentation:

switch($color . $size) {
   case 'bluesmall': ...
   case 'redlarge': ...
}

but that gets ugly pretty quick.

Answer 6

Using the new array syntax, this looks almost like what you want:

switch ([$color, $size]) {
    case ['blue', 'small']:
        echo 'blue and small';
    break;

    case ['red', 'large'];
        echo 'red and large';
    break;
}
