I recently discovered that the EE/CI's SLASH constant isn't the same as the "/" character. Or, at least, in my plug-in code, (SLASH == "/") evaluates to FALSE...

They output the same character, though. I'm confused... can anyone explain why this is the case?

That's because SLASH is actually the encoded form of /. Here's how it's set:

define('SLASH', '/');
  • Thanks, that make sense. I guess that means the constant isn't the best for use in regular expressions or [pre-parse] string replacements for templates. Nov 27, 2012 at 19:42
  • Yeah, I'd just ignore it, the EE core code does. Depending on what you're doing the DIRECTORY_SEPARATOR constant might be worth a look.

    AMP and other constants are also HTML-encoded. Always good to keep this in mind, they can be the cause of so many weird issues. Nov 27, 2012 at 20:22
