Permissions Mysql插入查询在php脚本中不起作用-权限问题？ 问题描述

我无法使用php写入Mysql表。本机命令行使用mysql客户端工作。但我可以在所有变体中进行“选择”——这似乎是一个权限问题，但是什么类型的？mysql凭据是相同的

我有一个全新的Debian7.6，安装了Apache、PHP和Mysql，所有这些都来自存储库。PHP是特殊的，我的应用程序需要PHP5.3。（原始7.6回购协议只有php 5.4）。所以我按照中的建议安装了PHP

你发布的代码有点循环。。。你能试试下面的菜吗？您的php测试似乎表明
INSERT
和
DELETE
这两种方法都有效（例如：
print\r（true）==1
）。
实际上，
mysql\u error（）
位于错误的位置。我会再检查一下。（目前我没有获得有关insert查询的信息，它是下面的select）
