How to use SonarQube in PHP programming?

As the amount and complexity of code increases, we need more efficient ways to perform code analysis and error repair. SonarQube is an open source code quality management platform that can perform code static analysis and measurement, including code complexity, duplicate code, defects, etc. SonarQube can help you better understand the code structure of the entire project, find potential problems, and provide reliable code quality indicators.

In PHP programming, SonarQube is also a very useful tool. Here are the steps on how to use SonarQube for PHP code analysis.

Step 1: Install SonarQube

First, you need to install SonarQube locally or on the server. You can download the corresponding version from the SonarQube official website and install it according to the instructions.

Step 2: Install PHP plug-in

SonarQube is extensible and supports multiple programming languages. You need to install the php plug-in and insert it into the plug-in directory of SonarQube. You can download it online or install it manually offline.

Step 3: Install PHP parser

SonarQube needs to be able to parse PHP code, therefore, you need to install a PHP parser. The method of installing a PHP parser may vary depending on the operating system. You can run php -v in the command line to see if the PHP parser is installed correctly, or you can run ./sonar.sh start in SonarQube to see if the parser is normal. Parse PHP code.

Step 4: Create SonarQube Project

Create a new project in SonarQube that will provide a container for your PHP code and receive SonarQube’s analysis results. Create a sonar-project.properties file under the project that contains metadata and properties about your project.

# Required metadata
sonar.projectKey=myproject
sonar.projectName=My Project
sonar.projectVersion=1.0

# Comma-separated paths to directories with sources (required)
sonar.sources=src

# Language specific properties
sonar.language=php
sonar.php.binaries=/usr/local/bin/php
sonar.php.tests=tests
sonar.php.coverage.reportPaths=coverage.xml

You need to replace sonar.projectKey with your project name, sonar.sources with the directory of your code, sonar.php.binaries Replace with the path to your PHP parser. If you have PHP unit tests, you need to add sonar.php.tests and sonar.php.coverage.reportPaths.

Step 5: Perform SonarQube analysis

After we have started writing a PHP project, we want SonarQube to analyze our code. For each branch, you can perform analysis on it. Here is a sample command:

./sonar-scanner.bat -D sonar.login=admin -D sonar.password=admin -D sonar.projectKey=myproject -D sonar.projectName=My Project -D sonar.sources=. -D sonar.host.url=http://localhost:9000

where sonar.login and sonar.password are the username and password for the SonarQube administrative account, sonar.projectKey## Replace # with your project name, sonar.sources with the code directory, and sonar.host.url with your SonarQube server address.

After executing this command, SonarQube starts analyzing your PHP code and provides information about the code quality. You can view the analysis results through the SonarQube interface, or view the log output through the command line.

Step 6: Solve the problem

SonarQube provides a rich report based on which you can find problems in the code, such as potential errors, code verbosity, code complexity, defects, etc. , solving these problems can greatly improve the quality and readability of your code. You can fix these issues through the solutions provided by SonarQube, or adjust the code manually.

Conclusion

Using SonarQube, you can easily analyze the PHP code of the entire project, find potential problems, and improve code quality. This process may take some time and work, but it can significantly improve the quality and readability of your code.
