How to use PHP for Alibaba Cloud development?
Alibaba Cloud is a leader among cloud service providers, and PHP is one of the most popular programming languages in the world. Novice developers may be confused about how to use PHP for Alibaba Cloud development, but this article will provide you with some guidance.
Necessary conditions for using Alibaba Cloud
Before you start using PHP for Alibaba Cloud development, you need to create an ECS instance on Alibaba Cloud and learn how to configure and manage the PHP environment on Alibaba Cloud. , and how to install and configure Apache server on ECS instance. In addition, you also need to master some basic PHP programming knowledge.
Installing PHP on the ECS instance
First, you need to install PHP using the yum package manager. Open the terminal and enter the following command:
sudo yum install php
After the installation is complete, you need to check whether it is installed correctly:
php --version
If it is installed correctly, you should see the version information of PHP.
Configuring PHP on Alibaba Cloud ECS instances
Before configuring PHP on Alibaba Cloud ECS instances, you need to know the location of the PHP.ini file. Usually, the PHP.ini file is in the /etc/php.ini directory.
Open the PHP.ini file, you can configure some important parameters of PHP, such as:
- Set the size limit of uploaded files
- Maximum execution time
- Memory Limitation
After configuring the PHP.ini file, you need to restart the Apache server for the changes to take effect.
Installing the Apache server on the ECS instance
On the Linux operating system, you can install and configure the Apache server through the terminal. First, use the yum package manager to install the Apache server:
sudo yum install httpd
After the installation is complete, you need to start the Apache server:
sudo systemctl start httpd.service
At the same time, you need to set the Apache server to start automatically when the system starts:
sudo systemctl enable httpd.service
After installing and configuring the Apache server, you need to check whether it was successful.
Running PHP scripts on ECS instances
When using PHP for Alibaba Cloud development, you need to run PHP scripts on the ECS instance through the Apache server. Go to the directory of the PHP file you want to run, for example /home/ec2-user/public_html/, and run the following command:
sudo chmod -R 755 /home/ec2-user/public_html/
This will give permissions to the /public_html directory and all subdirectories to be read by the Apache server files and display web pages.
Before running the PHP script, you need to write the PHP script. Open an empty file with a text editor and write a simple PHP script in it:
<?php echo "Hello, world!"; ?>
Save the file as hello.php and upload it to the /public_html directory on the ECS instance.
Finally, you can enter the public IP address of your ECS instance into a browser and then use a slash followed by the script file name to access your PHP script, for example:
http://127.0.0.1/hello.php
If If it runs successfully, you should see "Hello, world!" output to the browser window.
Conclusion
This article provides basic guidance on using PHP for Alibaba Cloud development. In addition, you can obtain more information and suggestions through the Alibaba Cloud official website and other developer communities. All in all, trying out and understanding these concepts in practice is the key to becoming a good developer.

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),
