Php 致命错误：类'；饼干'；找不到

我还在看那些教程，遇到了另一个错误，花了几个小时看了看，我看不出我又错在哪里了。基本登录不需要选中复选框记住我，我已经查看了我的数据库结构和文件名/类型和路径，尝试了var_dump，在我的资源中查找了是否未找到cookie文件的任何指示，所有内容都变成空的

您是否
在Users类中要求\u一次
cookie.php文件？根据您提供的代码，它不是必需的。在User.php文件中需要cookie.php。
我重新保存了该文件，复制了cookie.php文件，并重写了目录中的文件，无论出于何种原因，该文件都有效。
代码太多了。通常，您应该尝试提供一组仍然存在问题的代码。它还可以帮助您缩小原因范围，并可能帮助您自己找到问题。查看它，我可以想象使用
spl\u autoload\u register
注册的函数找不到您的
Cookie
类。您应该尝试在该函数中使用
getcwd
和
get\u include\u path
，以查看脚本实际查看的位置。我以前从未使用过这些函数，但这是它给我的答案，我将在问题中包括它，即使在中也找不到该类。该类位于cookie.php文件中。如果您确实
需要在php文件顶部添加一次（“cookie.php”）
，那么应该可以解决登录页面“core/init.php”的问题；这有spl_autoload_寄存器（函数（$class）{require_once'classes/'.$class..php'；}）；需要_once“functions/sanitize.php”，因此，它会自动加载类（理论上）它只为其余的类工作，而不是出于任何原因加载这个cookie类。不过，我确实按照你的建议试过了，但没用。
