Simple PHP+CSV

Write a PHP program that downloads stock quotes CSV from Yahoo from [login to view URL], for example, [login to view URL] will download a CSV of IBM. This should be a Linux console application (you can execute wget/curl), that in its command line receives several tickers (like IBM MSFT GOOG etc.), downloads them, and outputs the following output in CSV: // first line is titles Date,time_t,[login to view URL],[login to view URL],[login to view URL],[login to view URL],IBM.C/O,IBM.C/C,IBM.H/L,[login to view URL],[login to view URL],[login to view URL],.... 12-12-12,256826,100,101,99,100.5,.98,.1.01.... Where: C/O is the open/close (division) C/C is the close divided by the close of the previous day H/L is open/low time_t is the linux time_t for the date in the file. long int. there also should be a possibility to specify in the command line which of the columns above to output. The user can select to output only a part of them. In addition to the above specified columns, there should be another possibility to add more columns of the form IBM.Open.1 which will be the [login to view URL] on the previous day, and IBM.Open.2 which will be the [login to view URL] 2 days ago, etc. The command line interface should provide a simple way to specify this info, or instead of command line, a text config file. The code must be well documented, to be maintained by developers who are not familiar with PHP.
