| /** | ||
| * UniversalClassLoader implements a "universal" autoloder for PHP 5.3. | ||
| * | ||
| * It is able to load classes that use either: | ||
| * | ||
| * * The technical interoperability standards for PHP 5.3 namespaces and | ||
| * class names (http://groups.google.com/group/php-standards/web/final-proposal); | ||
| * | ||
| * * The PEAR naming convention for classes (http://pear.php.net/). | ||
| * | ||
| * Classes from a sub-namespace or a sub-hierarchy of PEAR classes can be | ||
| * looked for in a list of locations to ease the vendoring of a sub-set of | ||
| * classes for large projects. | ||
| * | ||
| * Example usage: | ||
| * | ||
| * $loader = new ClassLoader(); | ||
| * | ||
| * // register classes with namespaces | ||
| * $loader->registerNamespaces(array( | ||
| * 'Symfony\Components' => __DIR__.'/components', | ||
| * 'Symfony' => __DIR__.'/framework', | ||
| * )); | ||
| * | ||
| * // register a library using the PEAR naming convention | ||
| * $loader->registerClasses(array( | ||
| * 'Swift_' => __DIR__.'/Swift', | ||
| * )); | ||
| * | ||
| * // activate the autoloader | ||
| * $loader->register(); | ||
| * | ||
| * In this example, if you try to use a class in the Symfony\Components | ||
| * namespace or one of its children (Symfony\Components\Console for instance), | ||
| * the autoloader will first look for the class under the components/ | ||
| * directory, and it will then fallback to the framework/ directory if not | ||
| * found before giving up. | ||
| * | ||
