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

Hi, Good initiative :-) I have a small addition to #5 on the list (let's call it 5a, and a new sub-point (5.b)): 5a. If you want to set cookies with setCookie(), output header information with header() or equal, ensure that you have not outputed ANY characters. That includes whitespace before your starting <? or <?php too. 5b. If you really do need to output data before setCookie() or header() (a conditional redirect is one example), then use the output buffering functions (ob_start(), ob_end_clean(), ob_end_flush(), ob_get_contents(), ob_implicit_flush()).
