String compare on a bool
I'm pretty sure this is a simple fundamental flaw in my newb PHP knowledge, but I was surprised when the following happened:
$result is TRUE... so why is it considered equal to the string "email"? I'm guessing this is because, technically, it's a bool and it isn't false? So when it's compared against a string (e.g. "email") it returns true.
Should I change my method to return as the result as a string containing "true" (instead of return true; on success), or is there another way I should be doing this?
Thanks.
Solution
Yes, true is equal (==) to a non-empty string. Not identical (===) though.
I suggest you peruse the type comparison table.
