How to declare variable in one php file and access in other php file

Guys

I want to declare my site name in config.php so I can access this variable from all files like add.php. Please let me know how to do this without global_variable on. By default global_variable is off and I want to do this keeping it off?

You can declare ALL your variables in a 'my_vars.php' i.e. and then include this file into the rest of your files which require the variables :

include ("path/to/file/my_vars.php");

PHP:

or

require 'path/to/file/my_vars.php';

PHP:

 

Hi buddy

Thank you for help, it is working.

GCS

 

You are welcome MAN!
I'm glad to help!

 

I would suggest using CONSTANTS whenever possible if the values won't change, as they have global scope regardless

 

How to do that i.e. how to declare can you please give a sample command?

GCS

 

define() use that

 

define("CONSTANT", "Hello world.");

the above command is for declaring...and assigning value to it

and the below is used for printing..

echo CONSTANT; // outputs "Hello world."

 

Thanks a lot buddy. Is this variable in all script (different php files) automatically or I have to include this php file in all files like above?

You can also use $_SESSION

 

This may also useful.
