Hi

For a class, students are going to run an experiment on line. Each time
a subject runs, his/her data is appended to one giant text file. Their
own data set will be just one line starting with the keyword they gave
as identification.

The faculty does not want the students to be able to download and see
the giant data file. He wants the students to only download and see the
data that starts with their own identification tag.

in unix, filtering a file to keep only the line starting with code MCB
would look something like
tail -f your_file_name | grep MCB
from what I read.

Given the concerns the faculty has for protecting the database, what do
I need to look into to write a php script that would access the data
file, but only show a web page with the data corresponding to the
students identification code?

thanks for some direction, php functions, php keywords I need to look
into.
Anne
