刚下了下最新版的phpmyadmin
装上后输入用户名root然后点登录 （因为我在本地，所以root没有密码）
结果老是报访问被拒绝的错误
看了下权限的设置没什么问题呀，
网上也没找到好的答案，
与是根踪代码，原来在配置文件里面有句:
$cfg['Servers'][$i]['AllowNoPasswordRoot'] = false;
在libraries/common.inc.php的886行对他进行了验证
如果他是false的话，用户名如果是root用户，则密码不能为空，否则不进行验证，他默认情况下就是flase，把他改成true就行了，
我想这可能是他为了安全着想吧，让人一定设root密码，呵 呵，不过我认为在测试的时候有点不方便，一般本地的root用户都是空的
其衩他可以把提示语句改下，说是你的root密码为空，以当前的安全级别不允许登录
可以到XXX地方把设置改过来，这样可能会明白 些，单一个访问被拒绝太难找原因了！

Dependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AMSelect DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

PHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AMDependency 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.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
