I wanna make a banner exchange script with php where ppl place a piece of code (called the Prowler Exchange Code) on their site which displays all the reciprocal links.
Example is here. Please read it. This is what I wanna code.
So how can I do what Google AdWords and Adgridwork and Txtswap do. How the code has some variables in it and then it retrieves the data from a database.
I'll be grateful for your answer.
