PreReq Index

Hi Guys, So here's what I'm looking for as a result(ex):

array ('html'       => array('iOutput'  => array('iIO' => array() )),

      'xml'        => array('iInput'   => array('iIO' => array() )),
      'database'   =>  array('iData',
                             'aMySQL',
                             'aFile',
                             'iOutput' => array('iIO' => array())
                            )
     );

This is a requirement tree which will be populated via my method Ember::setPreReq(). I'm not sure how to develop this method properly, however. Ember::setPreReq() is a method I'm using as part of my framework that includes files needed by components in a clean manner, as well as allowing me map the requirements in an array that can be used for debugging purposes. Definition thus far: /*********** * Public Static Method getPrereq * INCOMPLETE * @param fpaFiles Array(String, Integer) ** * Allows files to get prerequisite files to be included and initilized * if required. * * fpaFiles format: * array( 'test.php' => Ember::mciSystem,

           'test2.php' => Ember::mciModule );

**********/

 const mciSystem    = 0;
 const mciModule    = 1;

const mciLibrary = 2; const mciInterface = 3; const mciException = 4; public static function setPrereq($fpaFiles) { global $gcSystemPath, $gcLibaryPath, $gcInterfacePath; foreach ( $fpaFiles as $fFile => $fType ) {

     switch ($fType) {
           //
       // mciSystem
       //
       case 0:
           break;
             //
       // mciModule
       //
       case 1:
           break;
             //
       // mciLibrary
       //
       case 2:
               $fFile = $gcLibraryPath . $fFile . '.php';
                   break;
             //
       // mciInterface
       //
       case 3:
               $fFile = $gcInterfacePath . $fFile . '.php';
                 if ( !file_exists($fFile) ) {
           throw new Exception("File '$fFile' does not exist", 1003);
         }
                 @include_once $fFile or ( throw new Exception("File '$fFile' could not be included.", 1003) );
             $this->maReqTree
           break;
             //
       // mciException
       //
       case 4:
           break;
     }

} } Example Call: Ember::setPrereq( array('iOutput' => Ember::mciInterface) ); Any help is apreceated. I'm not sure where to go next to build this array. Regards, - Craige
