For the site, you just have to remember what RSS is: plain text. All you have to do is to get PHP to output plain text that abides by the RSS specification.
Just like you would output HTML with echo or print, you can output the required RSS content. All you have to do is to ensure you all all the required elements (some are required, some are optional) and they are in the correct structure (ie. just like <body> is within <html>, or how <td> is within <tr> which is within <table> etc).
The easiest thing to do is to look at an example RSS document, and then look up each element in the spec to see what it's supposed to contain. After you know which elements are required and in what order, you can just copy the structure.
