Question

我正在尝试使用php上传文件，代码snippt

$upload_path = "/var/upload/" . $_FILES['mfile']['name'];
if(move_uploaded_file($_FILES['mfile']['tmp_name'], $upload_path))
    echo "file uploaded";
else
    echo "upload failed";

注意：/ var / upload目录存在且具有777权限。

代码打印“上传失败”

当我检查/ var / upload目录时，有文件f_505bf77bd8a0f_mypdf.pdf。出了什么问题？

添加了日志（根据loler的要求）：

添加了var_dump（$ _ FILES）

array(1) {
  ["mfile"]=&gt;
  array(5) {
    ["name"]=&gt;
    string(23) "mypdf.pdf"
    ["type"]=&gt;
    string(15) "application/pdf"
    ["tmp_name"]=&gt;
    string(26) "/var/tmp/phpUl6k50"
    ["error"]=&gt;
    int(0)
    ["size"]=&gt;
    int(478704)
  }
}

Answer 1

尝试使用此代码上传文件..

if (file_exists("/var/upload/" . $_FILES["file"]["name"]))
  {
  echo $_FILES["file"]["name"] . " already exists. ";
  }
else
  {
  move_uploaded_file($_FILES["file"]["tmp_name"],
  "/var/upload/" . $_FILES["file"]["name"]);
  echo "Stored in: " . "/var/upload/" . $_FILES["file"]["name"];
  }

Answer 2

在var_dump()中，$_FILES["file"]["name"]长度为23，但应为9.因此请尝试trim此字符串。而不是

$upload_path = "/var/upload/" . $_FILES['mfile']['name'];

尝试写

$upload_path = "/var/upload/" . trim($_FILES['mfile']['name']);

php move_uploaded_file强制给出新名称
