Question

我的客户端需要文件名与上传时的名称相同。但我需要将所有文件存储在同一个文件夹中。怎么样？或者处理这个问题的最佳方法是什么，这样我就可以让客户端以他上传的名字下载文件。

Answer 1

试试这个：

  $randString = md5(time()); //encode the timestamp - returns a 32 chars long string

  $fileName = $_FILES["uploaded_file"]["name"]; //the original file name

  $splitName = explode(".", $fileName); //split the file name by the dot

  $fileExt = end($splitName); //get the file extension

  $newFileName  = strtolower($randString.'.'.$fileExt); //join file name and ext.

Answer 2

$name = "foto";
$extension = ".png";

$today = date("Y/m/d-H:i:s");
$fullName = $name."_".$today.$fileExtension;
  //where $name was it's actual name
  //$today is todays date and time
  //$file extension would be something like ".png"

$fullName的值示例为foto_2001/03/10-17:16:18.png
