RE: PHP Boolean Interpreter - Need to search a mySQL database

This is no good because it doesn't check for single or double quotes.
Inputting anything with quotes gives ugly ugly errors. Plus, Boolean
interpreters should group quoted words as a single term. It doesn't
check for malicious code input at all. I tried editing it to make it
better, but after lots and lots of work, I didn't get very far. If you
can fix it up, let me know =)

Thanks for that link... that's a great piece of code!

With error reporting cranked right up it throws a few warnings,
but no errors. It certainly performs as described.

The only thing it doesn't seem to do is check for "+".
But adding that is a 30 second task.

If this isn't good enough for you, just what are you looking for?
