Using mysql, php, apache on win98
The following code is from "PHP, mySQL and Apache" (SAMS) by Julie Meloni.
Page 338-339 (hour 16).
After choosing my selections in the form box and hitting submit I get:
...............
Warning: Invalid argument supplied for foreach() in
c:\apache\htdocs\listing16.5.php on line 13
..................
I checked her errata at thickbooks.com but there was nothing for this
chapter.
Any help will be greatly appreciated.
Thank you.

Hi. I'm having difficulty getting the php_gd2.dll to load.
Running W2K server, IIS 5.0, PHP 4.3.1. I've modified the php.ini file and
set my extensions directory to C:\PHP and I've
uncommented extension=php_gd2.dll. When I do this, and attempt to load the
php test page, my browser attempts to load the page forever, with no
success. If I then comment it back out, the page loads, but of course
without the dll. I've tried to uncomment and load a couple of other dlls,
same result. And those I attempt to load are in the C:\PHP directory where
I assume they should be. Anybody have any suggestions?
Thanks.
Brent
