I have various 'code snippets' which rotate photos, pick random numbers, ect. This is something I can figure out, but I'm looking for a quick simple solution (without using PHPadsNew, for example) ~~~~~~~~~~~~ All I need is 'sharerev.php' (for example) which contains only the Adsense code for a writer, mod, or admin. ...and 'myrev.php' which has only my Google ad code Now I need a flexable, easy way to 'give 80%' to sharing and have mine appear ~20% of the time I'm 'OK' at modifying code, and just starting to learn to actually write. Please, give a 'basic framework' for randomly having one PHP file called on ~80% of the time, and just some ideas on a simple, basic 'actual usage example.' Thank you very much.
