Would be nice if you could give a simple example - i really have problems
working with interfaces :(
My problem was to design a filesystem structure with classes like this:
class Folder {
var $name;
var $path;
function init() {} // should set $name and $path...
function read($recursive = FALSE) {} // should read own content and
eventually all subdirs
}
class File extends Folder {
// inherited properties and funcs...
function read() {} // should read the file content, $recursive is not
needed
}
how could i implement my interfaces? I think interfaces wouldn't solve php4
compatibility problems...
best regards,
vivi
