Hi Omaha PHP'ers:
At the meeting yesterday we welcomed PerlMonger Jay Hannah.
The June handout is now posted here:
http://omaha.phpconsulting.com/
To address some of Jay's questions to the list, default variable scope is
global (even across includes and requires) meaning that it works for that
"hit". Helpful scope examples here:
http://www.php.net/manual/en/language.variables.scope.php
For session-specific variable space, use the $_SESSION array after
initiating a session with session_start().
Here's the scoop on php documentation: to get details on a function, type
in a url http://php.net/functionname. If the function name exists, it
will give you the documentation for it, if not, it will redirect you to a
google lookup with your search term. Appropriately, see:
http://www.php.net/implode
http://www.php.net/explode
At the end of the meeting we touched on a topic for next month, which will
be XML. I am by no means an expert in this area, so would anyone else
want to write up a one-page handout that we can talk over?
See you next month,
Mat Caughron
