Here's the issue. I have both the client and the server side parts done but with place holder values on the client page. I'm having issues figuring out how to get them to talk or rather pass variables to each other.
For simplicity lets work with a simple example and I can then apply that to my project. Say I have a php page or even a simple html/javascript(if possible) page that a user accesses via their web browser. I want to print or alert the variable $A.
Does this variable actually exist anywhere, or is it just sitting in some file?
What do you need to be able to do with this variable?

I have a server side shell script that simply assigns the variable $a to "hello."
Shell variables only make sense in a shell...
You could export the variable, then have your PHP executed like this:
But I get the feeling you want to have more control over the variable than that, you need to set and retrieve it when you please, not just when first executed, and do so in a manner safe across several connections.
This is the sort of thing they usually use a database with. The combination of Linux, Apache, Mysql and PHP is so common they usually call it LAMP...

LEARN ABOUT PHP
_env
_ENV(3) 1 _ENV(3)
$_ENV - Environment variables
An associative array of variables passed to the current script via the environment method.
These variables are imported into PHP's global namespace from the environment under which the PHP parser is running. Many are provided by
the shell under which PHP is running and different systems are likely running different kinds of shells, a definitive list is impossible.
Please see your shell's documentation for a list of defined environment variables.
Other environment variables include the CGI variables, placed there regardless of whether PHP is running as a server module or CGI proces-
sor.
$HTTP_ENV_VARS contains the same initial information, but is not a superglobal. (Note that $HTTP_ENV_VARS and $_ENV are different variables
and that PHP handles them as such)
+--------+---------------------------------------------------+
|Version | |
| | |
| | Description |
| | |
+--------+---------------------------------------------------+
| 4.1.0 | |
| | |
| | Introduced $_ENV that deprecated $HTTP_ENV_VARS. |
| | |
+--------+---------------------------------------------------+
Example #1
$_ENV example
<?php
echo 'My username is ' .$_ENV["USER"] . '!';
?>
Assuming "bjori" executes this script
The above example will output something similar to:
My username is bjori!
Note
This is a 'superglobal', or automatic global, variable. This simply means that it is available in all scopes throughout a script.
There is no need to do global $variable; to access it within functions or methods.
getenv(3), The filter extension.
