MySQL 쿼리의 각 결과를 하나씩 텍스트 파일에 저장하는 방법은 무엇입니까?

Question

while($row= mysql_fetch_object($result)){ 
    $row->products_price=$row->products_price-($row->products_price*0.05); 
    echo $row->products_id ." ". $row->products_price."<br/>"; 
} 

$row->products_id ." ". $row->products_price을 한 번에 한 행씩 txt 파일에 넣을 수 있습니까?
