Re: isset, empty, "" and the like

Yes, interesting indeed. Similar information also exists in a few user comments so perhaps it's time to put a table like this in the manual :) Appendix or faq? Some additions to php_cheat_sheet: a) Add boolean true to first table b) empty() handling of "0" changed in php4 c) forms only pass strings d) When E_NOTICE errors will result e) Difference of isset() and array_key_exists() in terms of how they treat NULL values. f) Add NULL to comparison tables g) Briefly mention and/or point to types section h) Mention ! i) Some other stuff no doubt... The color changes really help make it clearer and easier to read, let's use a similar color scheme instead of the &true; and &false; entities.
