我正在使用这段代码:

<?php

$ran = rand () ;
$ran2 = $ran.".";

$allowedExts = array("gif", "jpeg", "jpg", "png");
$extension = end(explode(".", $_FILES["file"]["name"]));
if ((($_FILES["file"]["type"] == "image/gif")
|| ($_FILES["file"]["type"] == "image/jpeg")
|| ($_FILES["file"]["type"] == "image/jpg")
|| ($_FILES["file"]["type"] == "image/pjpeg")
|| ($_FILES["file"]["type"] == "image/x-png")
|| ($_FILES["file"]["type"] == "image/png"))
&& ($_FILES["file"]["size"] < 2000000)
&& in_array($extension, $allowedExts))
  {
  if ($_FILES["file"]["error"] > 0)
    {
    echo "Return Code: " . $_FILES["file"]["error"] . "<br>";
    }
  else
    {
    echo "Upload: " . $_FILES["file"]["name"] . "<br>";
    echo "Type: " . $_FILES["file"]["type"] . "<br>";
    echo "Size: " . ($_FILES["file"]["size"] / 1024) . " kB<br>";
    echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br>";

    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: " . "filer.SITEHERE.com/upload/" . $_FILES["file"]["name"];
      }
    }
  }
else
  {
  echo "Invalid file or service down";
  echo "It must be an image to be uploaded.";
  }
?>

有什么办法可以让 ran2 成为文件名而不是原始名称?抱歉,我是 PHP 的初学者,找不到可行的方法。我想主要坚持这个脚本或至少制作它,以便他们只能上传一定大小的图像。

编辑:删除站点名称。

你根本没用$ran2。遵循 Ryan 的示例,但添加$extension,因为看起来您已经准备好附加它了..

所以:

move_uploaded_file($_FILES["file"]["tmp_name"], "/upload/" . $ran2 . $extension);

只需将第二个参数更改为move_uploaded_file,我还看到您没有添加扩展名,因此也应该添加它:

// Don't forget to add the extension
$extension = pathinfo($_FILES["file"]["name"], PATHINFO_EXTENSION);
move_uploaded_file($_FILES["file"]["tmp_name"],
  "upload/" . $ran2 . $extension);
