我对move_uploaded_file函数有问题。我不知道为什么它不起作用，也许是init.php路径有问题.我有几个相关的文件，所以我决定向您展示我的存储库： https://github.com/pchudzin/Learning-PHP-OOP/tree/master/PhotoGallerySystem 在这里你可以下载我的代码，还有数据库文件。
我的代码中有 2 条警告和错误消息("文件目录可能没有权限"(：
警告： move_uploaded_file(SITE_ROOT\admin\images\13-uklad-1.png(： 无法打开流：中没有此类文件或目录 C：\xampp\htdocs\kurs_OOP_PHP\Learning-PHP-OOP\PhotoGallerySystem\admin\include\photo.php 在第 62 行
警告：move_uploaded_file((： 无法移动 'C：\xampp\tmp\php1C1.tmp' to 'SITE_ROOT\admin\images\13-uklad-1.png' 在 C：\xampp\htdocs\kurs_OOP_PHP\Learning-PHP-OOP\PhotoGallerySystem\admin\include\photo.php 在第 62 行
图像文件夹的绝对路径：

图像文件夹具有读/写权限。
我将感谢您的帮助！ 初始化.php

它看起来像这样一行：
$target_path = 'SITE_ROOT' . DS . 'admin'. DS . $this->upload_directory . DS . $this->filename;
当您打算使用常量SITE_ROOT时，正在使用文字字符串"SITE_ROOT"。所以我认为你的台词应该读：
$target_path = SITE_ROOT . DS . 'admin'. DS . $this->upload_directory . DS . $this->filename;
