Conditional search using PHP/SQL: like 'browse' on Myspace

[lightnb]

I would love to code it myself, but am not expirienced enough with PHP to write a script from scratch. I wouldn't know where to start.

It doesn't neccessarily have to integrate with vB- it just has to be on a "vB compatible" page. (by vB compatible I mean able to access the vB log-in and permissions system)

The database that it is quererying is independant from the vB database. It's actually to browse microphones based on criteria:

For example, in my table 'microphones' I have fields: make, model, frequency response, max spl, etc..

The user should be able to go to a microphone browse form, choose 'Shure' in the "make" drop down box, and when they click submit, it returns a list of all microphones in the database whos make is shure.

I'm not even sure of where to begin- I guess i'd need to see an example, and could figure out how it works from that.
