Re: [PHP-DOC] isset, empty, "" and the like From: Philip Olson (philip <email protected>)

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.

Regards,
Philip
