The autoloader is slightly modified from PureMVC's site to suit my needs. Using namespace and everything that's PHP v5.3+, this is part of PureMVC framework that I've ported over from the original Flash code a while back. define( 'PMVC_BASE_DIR', str_replace( '\\', '/', __DIR__ ).'/' ); function __autoload( $class ) { if( stristr( $class, '\\' ) ) { $file = APP_DIR.str_replace( '\\', '/', $class ).EXT; if( file_exists( $file ) ) require_once $file; else throw new \Exception( 'Unable to find class '.$class. ' in the expected location '.$file ); } else { $_basePaths = array( PMVC_BASE_DIR.'org/puremvc/php/patterns/facade/', PMVC_BASE_DIR.'org/puremvc/php/interfaces/', PMVC_BASE_DIR.'org/puremvc/php/core/', PMVC_BASE_DIR.'org/puremvc/php/patterns/', PMVC_BASE_DIR.'org/puremvc/php/patterns/command/', PMVC_BASE_DIR.'org/puremvc/php/patterns/mediator/', PMVC_BASE_DIR.'org/puremvc/php/patterns/observer/', PMVC_BASE_DIR.'org/puremvc/php/patterns/proxy/' ); $classPaths = array_merge( explode( PATH_SEPARATOR, get_include_path() ), $_basePaths ); foreach( $classPaths as $classPath ) { $path = $classPath.$class.EXT; if( file_exists( $path ) ) { require_once $path; return; } } throw new \Exception( 'Unable to find class '.$class.' in '. implode( PATH_SEPARATOR, $classPaths ) ); } }
