//First Method with No Argument

$this->RestructArray($arrTempCounts)

//Second Method with  Column Name as Argument
$this->RestructArray($arrTemp, 'UserNums');

function RestructArray($parrInput, $pArg1 = 0)
{
	$arrTemp = $parrInput;
	
	for($i=0;$i<count($parrInput);$i++)
	{
		$arrNames[$i] = $parrInput[$i][$pArg1];
