Question

For example, I have a directory structure like this:

my_stuff
   classes
      one
      two
          more
          evenmore
              manymore
                  subsub
                      subsubsub
          otherstuff
          morestuff
              deepstuff
                  toomuch

and I want to add everything (!) under classes to the php include paths. How would I get such an array? Is there some fancy php func for this?

Answer 1

Recursively iterating over a Directory is easy with SplIterators. You just do

$path = realpath('.');

$elements = new RecursiveIteratorIterator(
    new RecursiveDirectoryIterator($path),
    RecursiveIteratorIterator::SELF_FIRST);

foreach($elements as $element){
    // element is an SplFileObject
    if($element->isDir()) { 
        echo "$element\n"; // do whatever
    }
}

However, do not add each directory to your include path.

If you add all these folders to the include path, you will severely slow down your application. If your class is in subsubsub, PHP will first search in my_stuff, then classes, then one, then two and so on.

Instead have your class names follow the PEAR convention and use autoloading.
