ช่วยดูให้หน่อยครับ หาผลรวมในตารางให้ได้ตามที่กำหนด

function CheckWantValue($amount, $arr){
	if(is_array($arr)){
		$output = [];
		$output['valid'] = true;
		$output['data']['in'] = [];
		$output['data']['out'] = [];
		$newArr = [];
		$wantValue = (int)$amount;
		foreach($arr as $arrK => $arrV){
			if($arrV >= $wantValue){
				$output['data']['in'][$arrK] = $arrV;
			}
			else{
				$output['data']['out'][$arrK] = $arrV;
			}
		}
	}
	else{
		$output['valid'] = false;
		$output['data'] = $arr;
	}
	return $output;
}

$data = [
	'A' => 7000,
	'B' => 5000,
	'C' => 5000,
	'D' => 15000,
	'E' => 20000,
];

print_r(CheckWantValue(7000, $data));
