RE: [PHP] Best practices for php application

[snip] Does anybody know of a url where I can find reading materials about best practices to organize the filesystem and variable structure of a php application? Although application purposes probably vary widely, I imagine that in one way or other most include adding, updating, deleting and displaying records, so there might be some standard or preferred procedure. [/snip] Having designed several large applications and examining several other large projects in PHP (and other languages) I can safely say that there are no particular rules, save for those common sense dictates (graphics in one location/directory, style sheets another, etc, includes another), for filesystem organization. We have a basic model that we start with, but past that it can get mangled pretty easily dependent upon the needs of the application itself.
