这篇文章介绍了php文件上传的简单实例,有需要的朋友可以参考一下

复制代码 代码如下:


if ((($_FILES["file"]["type"] == "image/gif")
|| ($_FILES["file"]["type"] == "image/jpeg")
|| ($_FILES["file"]["type"] == "image/pjpeg"))
&& ($_FILES["file"]["size"]   {
  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"]);//注释
      echo "Stored in: " . "upload/" . $_FILES["file"]["name"];
      }
    }
  }
else
  {
  echo "Invalid file";
  }
?>

因为php文件上传时会将文件存在一个临时文件夹,,如果没有对此临时文件进行移动,那么本脚本结束后会自动删除该临时文件。

因此以上注释那行代码是对上传文件进行保存。保存的目录为:当前目录下的upload文件夹下。
