I have a `Zend_Form_Element_MultiCheckbox` which has the values:

1. CSCI 5200 Software [FALL 2013]
2. CSCI 5200 Design [FALL 2014]

Now I need to split each value before I insert it into to the database. For example, the first value should be split into CSCI, 5200, Software and FALL 2013.

I tried this:

```
$course = $this->getValue(self::ELEMENT_COURSES);
foreach ($course as $item) {
    foreach($item as $key=>$value) {
        echo $value."\n";
    }

```

But it does not work.
