我是MySQLi的新手，我没有做MySQL和php的任何部分，但没有加载，我正在努力正确学习，但使用MySQLi是因为MySQL现在不推荐使用。。我的问题是，当我添加一些详细信息时，它会将我重定向到我想要的页面，就像添加详细信息时应该的那样，但它实际上并没有将任何信息插入数据库中，我尝试过查看phpMyAdmin，但它不起作用。。此外，当我单击编辑文件时，它会给我以下错误：致命错误：允许的内存大小为67108864字节，已在…中耗尽（试图分配4294967296字节）。。。。
这是文件：

您的某个列是LONGBLOB还是LONGTEXT？
PHP试图分配足够的内存来容纳该列的最大大小（4294967296字节）。请参阅此处（注意页面上的最后一篇文章）：
http://bugs.php.net/bug.php?id=51386
如果是这种情况，请将列更改为MEDIUMTEXT或MEDIUMBLOB，或者更小的列（如果可以的话）。
