Passing shell variables to a webpage

Use and complete the template provided. The entire template must be completed. If you don't, your post may be deleted!

1. The problem statement, all variables and given/known data:

This is my assignment as a whole - Use SVG to present certain dynamic (the raw data should change at least once a day) data visually. Consider using any of the conventional ways of that illustrating data (charts, figures, graphs, maps. etc.) or consider more experimental ways of visualizing data such as shown in the work of Edward Tufte or in some of the illustrations of similarity using OWL. Hopefully, your illustration will help guide insights about the data that might not be apparent to someone just looking at the raw textual or numeric data.

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. I have a server side shell script that simply assigns the variable $a to "hello." I want to somehow send that variable to my php/javascript page so that $A is also hello and the alert or echo/print is no longer blank.

Any ideas? I've used POST and GET to send data to a shell script before but its been a one way street with the shell script dynamically building the output page. Can I call the url of my cgi script and have that script then open the url of my webpage with parameters such as 'testpage.domain.com/?A=hello'

2. Relevant commands, code, scripts, algorithms:

Since I don't really want anyone to do my project for me I've outlined a simple example above so there isn't really any code to post.

3. The attempts at a solution (include all code and scripts):

I've not tried any actual coding yet because I'm not sure where to start with this but I've Google'd quite a few variations of my question to no avail.

4. Complete Name of School (University), City (State), Country, Name of Professor, and Course Number (Link to Course):

Slippery Rock University, Slippery Rock, PA, United States of America, Dr. David Dailey, CPSC 317

Note: Without school/professor/course information, you will be banned if you post here! You must complete the entire template (not just parts of it).

DROP TEXT SEARCH 
TEMPLATE(7)				  PostgreSQL 9.2.7 Documentation			      DROP TEXT SEARCH TEMPLATE(7)

NAME

       DROP_TEXT_SEARCH_TEMPLATE - remove a text search template

SYNOPSIS

       DROP TEXT SEARCH TEMPLATE [ IF EXISTS ] name [ CASCADE | RESTRICT ]

DESCRIPTION

       DROP TEXT SEARCH TEMPLATE drops an existing text search template. You must be a superuser to use this command.

PARAMETERS

       IF EXISTS
	   Do not throw an error if the text search template does not exist. A notice is issued in this case.

       name
	   The name (optionally schema-qualified) of an existing text search template.

       CASCADE
	   Automatically drop objects that depend on the text search template.

       RESTRICT
	   Refuse to drop the text search template if any objects depend on it. This is the default.

EXAMPLES

       Remove the text search template thesaurus:

	   DROP TEXT SEARCH TEMPLATE thesaurus;

       This command will not succeed if there are any existing text search dictionaries that use the template. Add CASCADE to drop such
       dictionaries along with the template.

COMPATIBILITY

       There is no DROP TEXT SEARCH TEMPLATE statement in the SQL standard.

SEE ALSO

       ALTER TEXT SEARCH TEMPLATE (ALTER_TEXT_SEARCH_TEMPLATE(7)), CREATE TEXT SEARCH TEMPLATE (CREATE_TEXT_SEARCH_TEMPLATE(7))
