PHP上传图像不工作

我在用php上传图片时遇到了一些问题。我不知道为什么,但我无法完成上传。 这是我的代码:

<?php

error_reporting(E_ALL);
$uploaddir = '/uploads/';
$uploadfile = $uploaddir . basename($_FILES['files']['name']['0']);

if (move_uploaded_file($_FILES['files']['name']['0'], __DIR__.'/../ticket/'. $_FILES["files"]['name']['0'])) {
    echo "Uploaded";
} else {
   echo "File was not uploaded";
}

echo 'Some Information:';
print_r($_FILES);

print "</pre>";

?>

这是我打电话给这家服务公司时收到的信息

 File was not uploadedSome Information:Array
 (
[files] => Array
    (
        [name] => Array
            (

            )

        [type] => Array
            (

            )

        [tmp_name] => Array
            (
                [0] => /membri/.dummy/temp/phpM2iSBN
            )

        [error] => Array
            (
                [0] => 0
            )

        [size] => Array
            (
                [0] => 112903
            )

    )

)

如果你能帮助我,谢谢你。
