PHP Reserved Words?

Anon

Hi, I'm a PHP newbie and before I create problems I can't diagnose properly, I'd like to know what PHP's reserved words are.

I can't seem to find these anywhere. php.net doesn't seem to list them.

Thanks for the help!

The "quick reference" list lists most of the reserved words except the "obvious" ones like IF THEN ELSE etc.

I guess that'll have to do...but I find it strange that there's no official list of reserved words. Or is it just me? 🙂

Thanks for the help.

Best thing to do is get a good editor that recognizes php. It will do things like change the color of reserved words. BBedit for the Mac is by far the best editor that I've used. look around, there will be a lot for your platform.

Well, most of the "reserved" words, really aren't reserved like in many other languages. The token are parsed in context and most (if not all) tokens can be used for other purposes outside their intended context. For example, the following code is perfectly legal:

$echo=12;
echo $echo;

Try it, it works.

Right, thats how they are parsed, but

But when you put a $ in front of it, your telling php that it is now a variable, meaning $echo is not a reserved word.

Regardless of how php treats these things internally, a text editor can quite easily tell the difference between, say, echo and $echo.

I've been using BBedit 6.0 for coding php for a while now (and I've used it for Perl for ages), and it works quite well.
