代码没错啊，为什么不对？？？

<?php 

$fileInfo=$_FILES['myFile'];

$filename=$fileInfo['name'];

$type=$fileInfo['type'];

$tmp_name=$fileInfo['tmp_name'];

$size=$fileInfo['size'];

$error=$fileInfo['error'];

//判断下错误号，只有为0或者是UPLOAD_ERR_OK，没有错误发生，上传成功

if($error==UPLOAD_ERR_OK)

{

if(move_uploaded_file($tmp_name,"uploads/".$filename)){

echo '文件'.$filename.'上传成功';

}else{

echo '文件'.$filename.'上传失败';

}

}else{

//匹配错误信息

switch ($error) {

case 1:

echo '上传文件超过了PHP配置文件中upload_max_filesize选项的值';

break;

case 2:

echo '上传文件超过了表单MAX_FILE_SIZE限制的大小';

break;

case 3:

echo '文件部分被上传';

break;

case 4:

echo '没有找到上传文件';

break;

case 6:

echo '没有找到临时目录';

break;

case 7:

case 8:

echo '系统错误';

break;

}

}
