Re: Things to check before you post (The Ultimate PHP Checlist)

Lars, Good idea, and in general principles it goes for any language. Four suggestions, do what you will with them: Read the manual (I know it's in there, but maybe repeat it once or twice). Read code aloud to somebody else. Wife, co-worker, it doesn't matter. It slows you down, you tend to explain as you go, and it forces you inoto a fresh look. Amazing how many times I've caught misplaced periods, unclosed brackets, etc. this way, or even gained a fresh insight into the algorithm. Is it a PHP problem or a database problem? If you're getting results, and processing them, but they are not the correct results, it's a database problem, not PHP.
