php day array

[koekie]

Hi i have the following php code:

function draw_measurepoint($pdf, $mp, $y) {
		if( empty($mp) ) return $y;
		$weekdays=array( 1=>'Ma', 2=>'Di', 3=>'Wo', 4=>'Do', 5=>'Vr', 6=>'Za', 7=>'Zo');
		$left=14;
		$scale=1; 		// Control this parameter to scale graph and scale.

but when is view the result of the pdf is doesn't show 7=>zo but only ma through za.

Any one an idea ?

Thanks in advandge

What is the code that uses the $weekdays array to draw the graph?
