问题
I am very new to PHP and am trying to find the best solution to my problem. In my database I have a field "painters". Within painters I have "painter A", "Painter B",and "Painter C". Is their a way to display painter c if certain art work comes up? Or Painter "B", if a certain art work comes up? I am trying to understand the best way to do something like this dynamically. Any links, code, or tutorials would help me tremendously! Thanks so much in advance!

You are going to want 3 tables. A "Painters" table, a "assoc" table, and a "Painting" table.
Painters table includes:
- ID
- Name
- DOB
- Phone
- Address
- Blah
- blah
Painting table includes:
- ID
- Name
- Date_Created
- Blah
- Blah
- Blah
Assoc table links them... It looks like:
- ID
- PAINTER_ID
- PAINTING_ID
So you can say SELECT PAINTING_ID FROM 'ASSOC' WHERE PAINTER_ID = '$Your_variable' Then with that result set iterate through that array with a foreach.
Inside that foreach: you will
SELECT * FROM PAINTINGS WHERE ID = Array['PAINTING_ID'].
That's a basic associative relational database.
You can google more about it, but that's the basics that should get you started

Start by reading these W3 tutorials.
http://www.w3schools.com/php/php_mysql_connect.asp
If you are like me and you need a visual aid then watch this tutorial, without this guy I wouldn't know anything about PHP, and I wouldn't have been able to creat my own CMS software, which I use for many of my clients.
For some reason the link won't post so Google "build a cms php youtube" and then click on the first video result :)
In future, it is good to try it yourself, and when you stumble upon problems, post on Stack Overflow, your question was a little to vague here.
