This is actually a much smaller data structure.

$colleges = array
(
 	'Blah Blah University' =>
        array
        (
            'physics' => array
                (
                    'sss',
                    'sffgg',
                ),
            'english' => array
                (
                    'sss',
                    'sffgg',
                )
	),
	'Glah Gleh University' =>
        array
        (
            'physics' => array
                (
                    'sss',
                    'sffgg',
                ),
            'english' => array
                (
                    'sss',
                    'sffgg',
                ),
        )
 );


foreach( $colleges as $collegeName => $depts )
{
     foreach( $depts as $deptName => $classes)
    {
        foreach( $classes as $className )
        {
            echo "$collegeName, $deptName, $className\n";
        }
    }
}
