Background description
Since the advent of php7, as the latest version control, I immediately upgraded to experience it, but due to the server There are still old programs running on the computer, so we have to deploy a PHP multi-version coexistence environment.
The existing environment is lnmp
- CentOS 6.7
- nginx 1.10.1
-mariadb-10.0.26
- php 7.0.8
In order to be better compatible with old php programs, it is recommended to use 5.4.45. It is mainly compatible with the mysql extension.
Start the installation
First download the php-5.4.45.tar.gz source package.
Install through source code

The above has introduced the coexistence of multiple versions of PHP deployed under Linux, including aspects of it. I hope it will be helpful to friends who are interested in PHP tutorials.

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.

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 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),
