 注意使用文件上传之前注意要加上这一句：

enctype="multipart/form-data"

 

显示图片 注意千万不要加入html的文件头，否则图片显示不出来

<?php
$id=$_GET["id"];
$link=mysql_connect("localhost","x0936008","x0936008");
mysql_query("set names utf8",$link);
mysql_select_db("x0936008");
$query="select image from personinfo where id=".$id;
$result=mysql_query($query);
list($img)=mysql_fetch_array($result);
echo $img;
mysql_close($link);
?>
