我想上传文件时在备份一个文件备份的文件名为上传文件名+上传人姓名+上传时间，
都不是汉字啊这是我的代码高手们帮帮看看，为什么报错

<form enctype="multipart/form-data" action="" method="post">

<table width="400" border="0" cellspacing="1" cellpadding="1" align="center" bgcolor="#E6E6E6" >

    <tr> 

      <td height="22" align="center" valign="middle" bgcolor="#F5F5F5" width="400"> 文件上传      </td>

    </tr>

    <tr align="center" valign="middle"> 

      <td align="center"  height="80" width="400" bgcolor="#FFFFFF"> 

	  选择文件:<input type="file" name="upload_file"  style="width:300">

	</td>		

    </tr>

    <tr align="center" valign="middle"> 

      <td bgcolor="#F5F5F5" height="24" width="400"> 

	    <div align="center">

          <input type="submit"  value="开始上传">

      </div></td>

    </tr>

  </table>

</form>

//$uploadFileName = $_POST['test'];

$ext = '.txt';

if(strrpos(@$_FILES['upload_file']['name'],'.') !== false){

    $ext = substr( @$_FILES['upload_file']['name'], strrpos(@$_FILES['upload_file']['name'], '.' ));

}

if(strtolower($ext) != '.txt' 

    && strtolower($ext) != '.jpg'

    && strtolower($ext) != '.gif' 

    && strtolower($ext) != '.png'

    && strtolower($ext) != '.doc'){

    echo '上传的文件类型不符合要求';

    exit;

}



$fileName = "E:\site_data/".'/'.date('Ymd').'/'.time().rand(100,999).$ext;            

move_uploaded_file(@$_FILES['upload_file']['tmp_name'],$_SERVER['DOCUMENT_ROOT'].'/'.$fileName);//这行报错

//

//$uploadfile="E:\site_data/".$_FILES['upload_file']['name'];

//if(move_uploaded_file($_FILES['upload_file']['tmp_name'],$uploadfile)){

//echo "成功";}

'D:/APMServ5.2.6/www/htdocs/E:\site_data//20100730/1280453764180.txt' in D:\APMServ5.2.6\www\htdocs\shangchuan.php on line 36

$upload_dir=="./site_data/";
$upload_bak="./site_data/";
//你至少要对$username赋予值.
$username = $_POST['username'];//提交过来的名字
//或者$username = $_COOKIE['username'];//cookie里的名字
$file=$_FILES['upload'];

$ext = explode(".",$file['name']);
$ext = $ext[count($ext)-1];
$filename1 = substr($file['name'],0,(strlen($file['name'])-strlen($ext)-1));
$bakfilename = "{$username}_".date("Y_m_d_H_i_s").".{$ext}";
if(move_uploaded_file($file['tmp_name'],$upload_bak.$file['name'])){
copy($upload_bak.$file['name'], $upload_bak.$bakfilename);
}

上传成功了但是备份文件的文件名没有上传人的名字只有时间大侠们帮我看看吧

$upload_dir=="./site_data/";

$upload_bak="./site_data/";



$file=$_FILES['upload'];



$ext = explode(".",$file['name']);

$ext = $ext[count($ext)-1];  

$filename1 = substr($file['name'],0,(strlen($file['name'])-strlen($ext)-1));              

$bakfilename = "{$username}_{$uid}_".date("Y_m_d_H_i_s").".{$ext}";

if(move_uploaded_file($file['tmp_name'],$upload_bak.$file['name'])){

copy($upload_bak.$file['name'], $upload_bak.$bakfilename); 

}

我之前也这样写过但是也是没有效果

$ext = '.txt';

if(strrpos(@$_FILES['upload_file']['name'],'.') !== false){

$ext = substr( @$_FILES['upload_file']['name'], strrpos(@$_FILES['upload_file']['name'], '.' ));

}

if(strtolower($ext) != '.txt' 

    && strtolower($ext) != '.jpg'

    && strtolower($ext) != '.gif' 

    && strtolower($ext) != '.htm'

    && strtolower($ext) != '.doc'){

    echo '上传的文件类型不符合要求';

    exit;

}

$fileName = date('Ymd').'/'.time().rand(100,999).$ext;

$base_folder = "E:/site_data/";       

if(move_uploaded_file(@$_FILES['upload_file']['tmp_name'],$base_folder.$fileName)){

人家已经写的很清楚了，\在php里是转义，就算你要用在路径上，至少也要加两个吧

感谢楼上的提示但是我改过后不报错但是上传文件后在 E:\site_data/文件夹中没有我上传的文件

$fileName = "E:\site_data/".'/'.date('Ymd').'/'.time().rand(100,999).$ext;            

//move_uploaded_file(@$_FILES['upload_file']['tmp_name'],$fileName);

//$fileName = date('Ymd').'/'.time().rand(100,999).$ext;            

move_uploaded_file(@$_FILES['upload_file']['tmp_name'],$fileName);

@copy($_SERVER['DOCUMENT_ROOT'].'/'.$fileName, "E:\site_data/".'/'.$fileName);

感谢大侠们赐教

你是越改越乱了！
$fileName = "E:/site_data/".date('Ymd').'/'.time().rand(100,999).$ext;
你需要保证相应的目录存在并可写
比如今天
E:/site_data/20100730
明天
E:/site_data/20100731

谢谢大家但还是报错说failed to open stream: No such file or directory in D:\APMServ5.2.6\www\htdocs\shangchuan.php on line 38



//$uploadFileName = $_POST['test'];

$ext = '.txt';

if(strrpos(@$_FILES['upload_file']['name'],'.') !== false){

    $ext = substr( @$_FILES['upload_file']['name'], strrpos(@$_FILES['upload_file']['name'], '.' ));

}

if(strtolower($ext) != '.txt' 

    && strtolower($ext) != '.jpg'

    && strtolower($ext) != '.gif' 

    && strtolower($ext) != '.htm'

    && strtolower($ext) != '.doc'){

    echo '上传的文件类型不符合要求';

    exit;

}



//$fileName = "E:\site_data/".'/'.date('Ymd').'/'.time().rand(100,999).$ext;            

//move_uploaded_file(@$_FILES['upload_file']['tmp_name'],$fileName);

$fileName = date('Ymd').'/'.time().rand(100,999).$ext;            

move_uploaded_file(@$_FILES['upload_file']['tmp_name'],$_SERVER['DOCUMENT_ROOT'].'/'.$fileName);//就是这行

@copy($_SERVER['DOCUMENT_ROOT'].'/'.$fileName, "E:\site_data/".'/'.$fileName);

我想让上传文件保存到E:\site_data/中

程序猿之殇 2010-07-30

$_SERVER['DOCUMENT_ROOT'] = 'D:/APMServ5.2.6/www/htdocs
$fileName你又给"E:\site_data/".'/'.date('Ymd').'/'.time().rand(100,999).$ext;传值了

两个构造在一起,肯定是不存在的路径了.

$fileName = date('Ymd').'/'.time().rand(100,999).$ext;            

move_uploaded_file(@$_FILES['upload_file']['tmp_name'],$_SERVER['DOCUMENT_ROOT'].'/'.$fileName);

@copy($_SERVER['DOCUMENT_ROOT'].'/'.$fileName, "E:\site_data/".'/'.$fileName);

既然你有
$fileName = "E:/site_data/".'/'.date('Ymd').'/'.time().rand(100,999).$ext;
那么就不需要而外指明路径了
move_uploaded_file(@$_FILES['upload_file']['tmp_name'], $fileName);

haihao_110 2010-07-30

这是最后调好的

$filename1 = substr($file['name'],0,(strlen($file['name'])-strlen($ext)-1));              

$bakfilename = $filename1."_{$uid}_{$username}_".date("Y_m_d_H_i_s").".{$ext}";

if(move_uploaded_file($file['tmp_name'],$upload_bak.$file['name'])){

copy($upload_bak.$file['name'], $upload_bak.$bakfilename); 

echo "上传成功";

你这样写又报错了Warning: copy(./site_data/PHP对数据库的操作.txt) [function.copy]: failed to open stream: No such file or directory in D:\APMServ5.2.6\www\htdocs\shangchuan.php on line 52
就是这句copy($upload_bak.$file['name'], $upload_bak.$file['name'].'_'.$bakfilename);
