HomeBackend DevelopmentPHP TutorialphpMyAdmin出现无法载入 mcrypt 扩展,请检查PHP配置的解决方法_php技巧

1、没有正确安装Mysql数据库,在系统服务中Mysql相关的服务没有启动 (请查看正确安装Mysql的方法)

2、在系统的 system32(C:\windows\system32) 目录下缺少 libmcrypt.dll文件,解决方法是找到php目录下的libmcrypt.dll,并将libmcrypt.dll复制到C:\windows\system32目录中,然后重新启动Web服务。

3、在C:\windows目录下的php.ini文件中,没有将“;extension=php_mcrypt.dll”中的前面一个“;”去掉,所以不能使用相应功能,解决方法是打开php.ini文件
找到
;extension=php_mcrypt.dll
改成
extension=php_mcrypt.dll //去掉前面的;使之生效

4、Mysql目录没有读取权限,正确的目录权限如下:
administrator 完全控制
system 完全控制

user 读取加运行
其他的用户权限全部删除(也可保留,但安全性不高,建议删除),然后重启MYsql服务和Web服务(建议修改此项后重启一下服务器)
当你试过所有办法之后还是不行,其实还有一步,网上很少有说,解决办法,我的是2003+IIS+PHP5+MYSQL5

名:phprc
值:c:\php(你的PHP在什么目录就是什么)

Dependency Injection vs. Service Locator in PHPDependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select 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 TestabilityPHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

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.

mPDF

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),
