php如何使上传图片时修改图片的名字，希望有源代码，我的代码如下，希望大哥大姐们能再我的代码上修改

<?php
include("head.php");
include ("conn.php");
if(is_uploaded_file(@$_FILES['upfile']['tmp_name'])){
$upfile=$_FILES["upfile"];
}
$name=@$upfile["name"];
$type=@$upfile["type"];
$size=@$upfile["size"];
$tmp_name=@$upfile["tmp_name"];
$error=@$upfile["error"];
if ($_FILES["tupian"]['error'] == UPLOAD_ERR_OK) {
$tmp_name = $_FILES["tupian"]["tmp_name"];
$name = $_FILES["tupian"]["name"];
move_uploaded_file($tmp_name, "$name");//在这里进行文件改名
}
echo '<img src="' . $name . '" />';

switch($type){
case'image/pjpeg':$ok=1;break;
case'image/jpeg':$ok=1;break;
case'image/gif':$ok=1;break;
case'image/png':$ok=1;break;
}
if(@$ok&&$error=='0'){
move_uploaded_file($tmp_name,'up/'.$name);
echo "上传成功";
}

if(@$_POST['submit']){
$sql="insert into message (id,username,title,content,latedate) values ('','$_POST[username]','$_POST[title]','$_POST[content]',now())";
if(mysql_query($sql)){
echo"添加成功";
}

Answer 2

你想以什么来命名？
$name = $_FILES["tupian"]["name"];
把这个改动就行
$name = ‘你改的文件名称';

追问
