Switch case with three parameters?

Question

Is it possible to use three parameters in switch-case, like this:

switch($var1, $var2, $var3){
    case true, false, false:
        echo \"Hello\";
        b         


        

Answer 1

You don't have a switch situation here. You have a multiple condition:

if($var && !($var2 || $var3)) { ...

Answer 2

I don't know - if you really want it this way - maybe cast them all to string, concatenate and then use the resulting string in your case condition?

Answer 3

Another option is to create a function that maps three parameters to an integer and use that in the switch statement.

function MapBool($var1, $var2, $var3){
    // ...
}

switch(MapBool($var1, $var2, $var3)) {
    case 0: 
        echo "Hello";
        break;
   // ...

}

Answer 4

I would just use the if/else

if($var1 == true && $var2 == false && $var3 == false){
    echo "Hello";
}

or

if($var1 && !($var2 && $var3)) {
    echo "Hello";
}

Answer 5

The syntax is not correct and I wouldn't recommend it, even if it was. But if you really want to use a construct like that, you can put your values into an array:

switch (array($var1, $var2, $var3)) {
    case array(true, false, false):
        echo "hello";
        break;
}

Answer 6

i don't think your syntax is valid.

I'd nest the switch statements.
