asked on

a global config variable that can be read from everywhere

I have procedural code mixed with object oriented code
Computes my hours and shows emails so I can present to client

so I want to work on code at the same time to make more re-usable

but there are many limitations

I have two separate table names for two companies, because I do not want to mix data.
So I would different php file for each company.
So I have to find and replace the tablename.
Maybe a config variable would be easier.
How to have a config variable that can be in object oriented classes and procedural functions.

I know that globals are bad but my old code is so disorganized.

I am not sure if $_session works in a procedural function and an object oriented class.
I may have to create and read the session in many times in the code.

what is a config variable

I have been asking experts-exchange questions about code where

$config['default_username']
$config['default_password']

and I think these variables can be read throughout the code

but is it just using the word '$config' that makes this possible?

The variable $config has no special meaning in PHP.

okay, for this example because I do not want to write many lines of code to start session and read session from every class method, how can I set a global variable one time and be able to read the global variable in every procedural function and object oriented class method on the same page?

Yes I read many times that global is bad but this code is not public and global may be the solution for this example and I will learn why global is bad by using in this example.

thanks for teaching me that a variable can have different values inside functions, classes
