I have been battling with a query that will assist me .
My previuos thread http://www.sitepoint.com/forums/show...=1#post1647117 under the php section has helped abit as well.
What I have is a html form with a set of health symptoms,that will be inserted into a database using implode() in php, I will extract the data using explode() in php.
Now if I take a condition like diabetes, when someone fills in a assessment , I want to know what other symptons were filled in together with diabetes, and how often.
Basically I want to be able to extract the most common symptons that were selected together with diabetes.
See my post above if unclear.
Please help me , I need this for my college project.
