Hello.

I'm trying to make the switch statement follow a strict comparison model as opposed to the default loose method (in other words, use === instead of ==) in order to make it respect data types.

<?php
switch ($value) {

    case '0':
        echo 'string zero';
        break;

    case 0:
        echo 'dec zero';
        break;

    case '':
        echo 'empty string';
        break;

    case null:
        echo 'null';
        break;

    case false:
        echo 'bool false';
        break;

    default:
        echo 'default';
        break;
}

?>

Bare in mind that you're asking PHP, an interpreted high-level language, to juggle types on the fly. You're better off doing a type-check first before proceeding to the conditional loop.

Yeah, and he's asking precisely how to have PHP not juggle types.

switch (true) {

    case $value === 0:
        echo 'dec zero';
        break;

    case $value === '':
        echo 'empty string';
        break;

    case $value === null:
        echo 'null';
        break;

    case $value === false:
        echo 'bool false';
        break;

    default:
        echo 'default';
        break;

}

Celeri's approach is probably the best.

Alternatively you can try basic typecasting: switch((string)$value).

Thanks all, I'll try these methods.
