为什么mysql_fetch_array/assoc + foreach只能遍历一条记录

foreach(mysql_fetch_array($result) as $key=>$row){<br />
							<br />
					 	print_r($row);<br />
									<br />
				} 


这样只能遍历输出最后一条记录

下面这样就能全部遍历,是不是说明数据库返回的数组与平常的不同?

while($row=mysql_fetch_array($result)) <br />
{ <br />
       $rows[]  = $row; <br />
} <br />
<br />
foreach($rows as $k => $v) <br />
{ <br />
   foreach($v as $vv){<br />
     echo $vv;<br />
   }

mysql_fetch_array ?foreach
