How to use phpDocumentor to generate documents in php?

As developers, we often need to write documents to record the functions and usage of the code. Especially when developing large projects, documentation is even more significant for maintainability and scalability. phpDocumentor is a tool for generating PHP code documents. It can automatically generate standardized and easy-to-read documents, allowing developers to better understand the code structure and usage. So before using phpDocumentor to generate documents, we need to first understand the correct use of phpDocumentor and install phpDocumentor.

Installing phpDocumentor

The installation of phpDocumentor can be performed through Composer. First, you need to ensure that Composer is installed on your computer. Then, before installing phpDocumentor, we must first execute the following command on the command line to globally install Composer's phpdocumentor/phpdocumentor package.

composer global require phpdocumentor/phpdocumentor

After the installation is complete, we can check the version information of PHPdoc through the following command:

phpdoc --version

Use PHPDocumentor

Next we can start using phpDocumentor to generate documents . First, create a new folder named "docs" in the project root directory to store the generated documentation. Then, enter the following command in the terminal:

phpdoc -d path/to/source -t path/to/output

Among them, the -d option is used to specify the source code directory to be scanned, and the -t option is used to specify the target directory for generating documents. For example, to generate documentation for a project named MyProject and store it in the /Users/username/Sites/myProject/docs directory, you can use the following command:

phpdoc -d /Users/username/Sites/myProject -t /Users/username/Sites/myProject/docs

When we run this command, phpDocumentor will scan all PHP files in this directory and generate an HTML file named index.html in the output directory. This file is the document for the entire project. In addition, phpDocumentor will also generate other files, including configuration files and resource files, which usually do not require manual modification.

If we want the document to be opened in the browser immediately after it is generated, we can add the --template=clean option to the command line. For example, the following command opens the /Users/username/Sites/myProject/docs/index.html file:

phpdoc -d /Users/username/Sites/myProject -t /Users/username/Sites/myProject/docs --template=clean

Modify the document homepage

The generated document uses the default theme by default, and its style may be different from ours projects are different. If we want the document to be displayed in a completely customized page when it is opened, we can do this by creating a custom template.

Here we demonstrate how to change the document homepage. The theme used by default when generating documents can be found in the "vendor/phpdocumentor/template-" directory in the project directory.

Take changing the following directory as an example:

vendor/phpdocumentor/template-clean/index.html

You can modify this file to change the document homepage and modify the style, layout and content. By modifying this file, we can customize the appearance and content of the document home page to better match our project.

Conclusion

By using phpDocumentor, we can avoid the trouble caused by manually writing documents and clearly view all the project's documentation comments on interfaces, classes and methods in the automatically generated documents. At the same time, we can also write these comments more easily, making the project easier to maintain. In actual project development, we can use these documents to better understand the code architecture and functional characteristics of the project, so as to carry out development work more efficiently.
