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.
