Practice PHP writing standards: an action guide to improve work efficiency and code quality

In the current field of software development, PHP is the most popular and widely used language one. However, due to the uneven level of developers, many projects have uneven code quality and low maintainability. In order to improve work efficiency and code quality, this article will introduce some action guidelines for practicing PHP writing standards.

1. Choose the appropriate coding style

Choosing the appropriate coding style is the first task in writing standardized code. Common coding styles include the specifications proposed by PSR-1 and PSR-2, as well as coding styles that make the code more readable, such as using semantic naming, appropriate indentation and line breaks, etc. Here is an example:

class HelloWorld
{
    private $message;

    public function __construct($message)
    {
        $this->message = $message;
    }

    public function sayHello()
    {
        echo $this->message;
    }
}

2. Focus on code readability

The readability of code is crucial to maintaining a project. To improve code readability, you can use comments and documentation blocks to explain the function and purpose of the code. At the same time, reasonable use of spaces, newlines, and indentations also contributes to code readability. Here is an example:

/**
 * 获取指定用户的详细信息
 *
 * @param int $userId 用户ID
 * @return array 用户详细信息的关联数组
 */
function getUserInfo($userId)
{
    // 查询用户信息
    $userInfo = [];

    return $userInfo;
}

3. Use naming conventions

Good naming conventions can improve the readability and maintainability of your code. The naming of variables, functions, classes, etc. should clearly reflect their purpose and meaning. Here is an example:

function calculateTotalPrice($unitPrice, $quantity)
{
    $totalPrice = $unitPrice * $quantity;
    return $totalPrice;
}

4. Conduct regular code reviews

Regular code reviews can detect and correct problems in time and improve the quality of the code. Code reviews should involve other people on the team with the goal of identifying potential issues and improvements. An example of a code review could be as follows:

// 不推荐的写法
if ($a == 1) {
    // do something
} else if ($a == 2) {
    // do something
} else if ($a == 3) {
    // do something
}

// 推荐的写法
if ($a == 1) {
    // do something
} elseif ($a == 2) {
    // do something
} elseif ($a == 3) {
    // do something
}

5. Using version control

Version control is an essential tool in team collaboration. Use version control to track code changes and revert to any previous version. The most popular version control system currently is Git. The following is a sample command using Git:

$ git clone <repository_url>  // 克隆远程仓库
$ git add <filename>  // 添加文件到暂存区
$ git commit -m "commit message" // 提交到本地仓库
$ git push origin master // 推送到远程仓库

Summary:

By practicing the action guide of PHP writing standards, you can improve work efficiency and code quality. Choosing an appropriate coding style, focusing on code readability, using naming conventions, conducting regular code reviews, and using version control are important aspects of improving code quality. I hope this article can help you write better code in PHP development.
