Don't use the @ sign, it is bad practice.

I'm not sure what this is for.

it is strange...
if I do this:
function nextRecord(){
$this->[EMAIL PROTECTED]($this->queryID);
$test=$this->record;
echo $test;
$status=is_array($this->record);
return ($status);

"Array" is echoed for $test so I know it is an array but if I add this:
shuffle($test);
I get the warning that
10 matches
