我的脚本有问题。它在我的托管服务器中上传图像。第二天或下周托管服务器缺少已创建的包含图像的文件夹，当然并非所有图像 - 18-19% 的图像持续 2 周。我问他们。他们告诉我——问题出在我的 php 代码中。如果有人可以帮助我会很高兴。可以我在 mkdir() 中添加一些 0777 吗？？？？我不知道。我一直在想...

<?php

    $file_ext=strtolower(end($extension));

试试这个以有效地查看 mkdir 创建是否失败。否则文件夹和图像即使添加到您的数据库中也肯定不会存在。

//previous code...
mkdir("files/$code");
mkdir("files/thumbs/$code");

//change to this...
if (!mkdir("files/$code", 0777, true)) {
    die('Failed to create folders...');
}

if (!mkdir("files/thumbs/$code", 0777, true)) {
    die('Failed to create sub folders...');
}
