HomeBackend DevelopmentPHP Tutorialphpredis - 如何安装php扩展

现在我正想安装一个redis的php扩展,原来的php是用yum安装的,版本是5.3

现在下载了一个redis扩展包phpredis,编译成了一个.so文件,并且在php.ini中打开了这个扩展,可以我用phpinfo显示信息的时候,却没有redis的信息,是不是因为我没有把.so文件拷贝到什么位置导致的呢?

求指点感谢!

ps:扩展安装步骤是:

phpize ./configure make && make install

edit: php.ini扩展信息已加过了。

edit: php.ini是phpinfo中的php.ini,现在调用redis也是生效的,但是我就是不知道为什么phpinfo中没有redis的信息):

查看 phpinfo() 中加载的 php.ini 的位置,在对应的 php.ini 文件中修改配置

` display_errors = On

displaystartuperrors = On `

重启 PHP (试 PHP 的运行方式重启 CGI 或者 Apache),注意启动时的提示信息中是否有错误,如果有错误按照提示错误信息修正。

贴php.ini里面加载扩展的配置。

  1. cgi重启了么?
  2. 确认你改的php.ini是不是你的cgi用的php.ini,在phpinfo里看
  3. make install成功以后会提示你 so 文件的位置,去看一下那个位置有没有文件

Dependency Injection in PHP: Code Examples for BeginnersDependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

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.

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),
