[PHP] Switch with different types

Author	Message
Posey	# Posted yesterday
	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; } ?> Obviously this code doesn't work the way I intend it to. What are some solutions other than switching to if/else.

	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.
