This autoload function searches for the class Location before requiring it. So there's no need
of putting the classes all in one folder.
Requirements:
- the subfolders must be at least 3 letters long
- the filenames must be in the form CLASSNAME.class.php
Note:
- in this example the main class folder is 'lib'
define('ROOT_DIR', dirname(__FILE__).'/');
function __autoload($className) {
$folder=classFolder($className);
if($folder) require_once($folder.'/'.$className.'.class.php');
}
function classFolder($className,$folder='lib') {
$dir=dir(ROOT_DIR.$folder);
if($folder=='lib' &&
file_exists(ROOT_DIR.$folder.'/'.$className.'.class.php')) return $folder;
else {
while (false!==($entry=$dir->read())) {
$checkFolder=$folder.'/'.$entry;
if(strlen($entry)>2) {
if(is_dir(ROOT_DIR.$checkFolder)) {
if(file_exists(ROOT_DIR.$checkFolder.'/'.$className.'.class.php')) return
$checkFolder;
else {
$subFolder=classFolder($className,$checkFolder);
if($subFolder) return $subFolder;
}
}
}
}
}
$dir->close();
return 0;
}
