		if ($answer_result == 1){ // User answered the question correctly
			$stat_01_pieces[1] = ($stat_01_pieces[1] + 1); // Adds 1 to the correct tally statistic for that question
		}else{
			$stat_01_pieces[2] = ($stat_01_pieces[2] + 1); // Adds 1 to the incorrect tally statistic for that question
		}
	//$a = "h".$stat_01_pieces[0].",".$stat_01_pieces[1].",".$stat_01_pieces[2];
	//$stat_01_data[$stat_01_handle] = $a;
	[b]print_r($stat_01_data);[/b]
	echo("A: ".$a);
	echo("SH: ".$stat_01_raw[$stat_01_handle]);
	for 
	fwrite($stat_01, $stat_01_raw);
	fclose($stat_01);
}
?>

 

The data is in the first array when I print it. However by the end of the function it is no longer in that array (I need it be be, while I have changed on of the contents of one of the array values). When I try to print the array at the end the data is not in an array, why??? How can I achieve what I mentioned above (change the contents of one of the array values).  Thanks

If you are getting the $variables by

global $stat_01_handle, $answer_result;

 

Why are sending them again to the function?  :

function stat_01($stat_01_handle, $answer_result)

 

 

remove the function parameters:

function stat_01()

 

But still use the globals:

function stat_01() {

global $stat_01_handle, $answer_result;

I done that, although the code does not work still.
