Stock Ticker Program - Coded in Perl, Python, and PHP

I need to create a relatively simple program in three languages: Perl, Python, and PHP.  It needs to be coded in these three languages and is due on 9/16/2015.  Please only contact me if you are sincere in your work, can use documentation for code, and know Perl/Python/PHP.  I previously worked with someone who copied/pasted code from Google resulting in a failure!

The simple programs are all the same: a stock ticker program (pull values for a stock from a site like Yahoo Finance, for example)

The criteria for the programs are:

Program written in Perl, Python, and PHP

- The prorgam should contain a some logic (solve some basic problem). 

- The program should do some input and output. The input and output could be:

-- read and write to a file

-- read and and and write XML

-- read and write data over the network

You will have one week to complete this assignment. You will be graded on this assignment. See how I grade coding assignments for details

You will be asked to write this program in Perl, Python, and in PHP. 

- A simple stock ticker (pull ticker value from finance site like Yahoo Finance, for example)

Criteria:

Documentation 

Works as described

Quality of code

 - easy to read / maintain 

 - good program structure and flow, parts logically broken out into methods or functions

 - some program logic 

 - some I/O 

Extra credit for test code 

If your project is more than one file, submit an attachment of a compressed archive of those files using either .zip or .tar 
If your project is a single file, it is ok to submit just the file as an attachment. 

Do not
 - use a compression tool other than zip or tar
