phpMyAdmin允许空密码登录的配置方法
当你将phpmyadmin登录密码设置为空密码时,尽管你通过Mysql命令行方式可以以空密码进入Mysql,但是当你重新以空密码登录phpmyadmin时却无法登陆。
这是因为默认phpmyadmin空密码登录是被禁止的,如果想要phpmyadmin空密码允许登录,就需要修改phpmyadmin相关配置。
如果想要允许phpmyadmin以空密码方式登录,就要修改libraries/config.default.php配置文件(如果你是以根目录下config.inc.php配安装phpmyadmin的,请一并检查)。
默认phpmyadmin空密码登录是被禁止的,这一行为主要通过配置文件libraries/config.default.php中的两个全局变量控制,即:
$cfg['Servers'][$i]['nopassword'] = false; $cfg['Servers'][$i]['AllowNoPassword'] = false;
只要修改这两个变量,设定为True,phpmyadmin就会允许以空密码方式登录,即修改libraries/config.default.php中的:
$cfg['Servers'][$i]['nopassword'] = true; $cfg['Servers'][$i]['AllowNoPassword'] = true;
同时将:
$cfg['Servers'][$i]['password'] = '';
设置数据库连接密码设为空密码,即告成功。
注意事项
在允许phpmyadmin空密码登录时,往往只修改:
$cfg['Servers'][$i]['AllowNoPassword'] = true;
这是不对的,空密码登录phpmyadmin仍然登录不了的,必须以上三个配置变量都修改。
在修改完phpmyadmin配置文件config.default.php后,重新以空密码方式登录phpmyadmin有时仍无法登陆。
这是因为cookie原因造成的,你需要关闭原有的phpmyadmin登录窗口,重新打开一个新窗口,这时空密码登录就没问题了。

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

PHP performance bottlenecks can be solved through the following steps: 1) Use Xdebug or Blackfire for performance analysis to find out the problem; 2) Optimize database queries and use caches, such as APCu; 3) Use efficient functions such as array_filter to optimize array operations; 4) Configure OPcache for bytecode cache; 5) Optimize the front-end, such as reducing HTTP requests and optimizing pictures; 6) Continuously monitor and optimize performance. Through these methods, the performance of PHP applications can be significantly improved.
