Using $GLOBALS in a function within a class

bnisperos

Code reference from the book by wrox: Professional PHP 4:

I am trying to get the statement

$this->msg_no = $GLOBALS["msg_no"];

to work within my function which resides in a class. My error statement is the following:

Notice: Undefined index: msg_no in C:\Apache2\htdocs_development\webmail\webmail2.php on line 46

The catch is that my server online works fine.

MY SETUP:
WORKSTATION SETUP: WAMP(win2k, apache 2.0.43, mysql, PHP 4.2.4 dev).

SERVER SETUP: FreeBSD, PHP 4.2.2

Question: Is this a linux specific statment? or is there a setting on my workstation that I need to fix?

Can you post your function delcaration?

Why not just declare the global at the beginning of your function.

global $msg_no;

then you can do

$this->msg_no = $msg_no;

Actually figured it out right after I posted the message.

I didn't define the $GLOBAL on the page I was creating the class.

But I am still wondering why PHP didn't just create an index for the variable. (Running it on the Free BSD server works fine.)

In php.ini, you can set error_reporting as you like. The BSD server has a setting that doesn't warn about about poor programming techniques (undefined vars/indexes etc...) and just cleans up the mess as it goes.
