Constructor & Destructor Documentation

__construct()

assAnswerCloze::__construct	(	string	$answertext = "",
		float	$points = 0.0,
		int	$order = 0,
		int	$id = -1,
		int	$state = 0
	)

assAnswerCloze constructor

The constructor takes possible arguments an creates an instance of the assAnswerCloze object.

Parameters

string	$answertext	A string defining the answer text
double	$points	The number of points given for the selected answer
integer	$order	A nonnegative value representing a possible display or sort order See if the initialization of the bounds to null can be avoided to have them string/numeric at all times.
