I'm attempting to throw an exception using php 5.3.2 and it is giving me the following error:

Parse error: syntax error, unexpected T_THROW

I am attempting to throw an exception the following way:

throw new Exception('Property ' . $name . ' doesn\'t exist in class Index', '');

Edit: I also tried

throw new Exception('Property ' . $name . ' doesn\'t exist in class Index');

it didn't change the error I was getting.

The complete method:

public function __get($name) 
    {
        if(property_exists($this, $name)
            throw new Exception('Property ' . $name . ' doesn\'t exist in class Index');
        return $this->$name;
    }
