RE: [PHP] == vs = should generate a warning or error -- was: Why won't this work?

Wow, that should have been a quiz. I can't believe how many people missed the == vs = thing and had all these elaborate answers. *grin* Which brings me to my point. Rasmus or any other PHP duder out there -- what are the possibilities of adding a config option in php.ini to WARN or ERROR when you try to use = instead of == in conditional checks like that. I can't tell you the number of minutes/hours wasted debugging code that turned out to be that stupid mistake. While it's handy to use an assignment in the conditional part, it can easily be done otherwise and I for one would be glad to never use it to save me valuable time tracking that down. Most other languages don't allow it.
