求教，该怎样解决？？？我的代码运行在linux上
upload_file.php:
if ((($_FILES["file"]["type"] == "image/gif")
|| ($_FILES["file"]["type"] == "image/jpeg")
|| ($_FILES["file"]["type"] == "image/pjpeg")))
{
if ($_FILES["file"]["error"] > 0)
{
echo "Return Code: " . $_FILES["file"]["error"] . "
}
else
{
echo "Upload: " . $_FILES["file"]["name"] . "
echo "Type: " . $_FILES["file"]["type"] . "
echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb
echo "Temp file: " . $_FILES["file"]["tmp_name"] . "
if (file_exists("upload/" . $_FILES["file"]["name"]))
{
echo $_FILES["file"]["name"] . " already exists. ";
}
else
{
move_uploaded_file($_FILES["file"]["tmp_name"],
"upload/" . $_FILES["file"]["name"]);
echo "Stored in: " . "upload/" . $_FILES["file"]["name"];
}
}
}
else
{
echo "Invalid file";
}
?>
------解决方案--------------------
目标目录不存在
请不要自行处理错误
贴出 print_r($_FILES["file"]); 的结果
------解决方案--------------------
$type=strrchr($_FILES["file"]["name"],"."); //获取扩展名
move_uploaded_file($_FILES["file"]["tmp_name"],
"upload/" . time().$type); //以当前时间戳命名
------解决方案--------------------
以时间戳明名是不错，但是有其他的好的方法吗
------解决方案--------------------
当然能，跟原来一样，还是在upload文件夹里面。
------解决方案--------------------
在文件名的前面加上了时间, 可以看看time()函数.
------解决方案--------------------
move_uploaded_file($_FILES["file"]["tmp_name"],
"upload/" . time().$type); //以当前时间戳命名
当你用这一行代码的时候,文件名加上时间戳.好好检查一遍吧.
------解决方案--------------------
如果出现错误，一步一步的来排查
