Standardized PHP writing: achieving efficient and clear coding style

Introduction:
PHP is a scripting language widely used in web development, with flexibility, However, in large-scale projects, code readability and maintainability have become challenges faced by developers. In order to improve the quality of code, standardizing PHP writing has become particularly important. This article will introduce some common normalization methods to achieve efficient and clear coding style.

  1. Naming convention
    Naming is an important part of the code. Good naming conventions can increase the readability and maintainability of the code. The following are some commonly used naming conventions:
  • Class name: use big camel case naming method, such as: MyClass
  • Method name and function name: use small camel case naming method, such as : myMethod
  • Variable name: Use camel case naming method, such as: myVariable
  • Constant name: all capital letters, separated by underscores between words, such as: MY_CONSTANT

Example:

class MyClass {
    public function myMethod($myVariable) {
        const MY_CONSTANT = 10;
        // code here
    }
}

  1. Indentation and Spaces
    The correct use of indentation and spaces can increase the readability of the code. It is recommended to use 4 spaces for indentation and a space after operators and commas.

Example:

function myFunction($param1, $param2) {
    $result = 0;
    foreach ($param1 as $item) {
        if ($item > $param2) {
            $result += $item;
        }
    }
    return $result;
}

  1. Comment specification
    Comments of the code are very important, it can help to read and understand the meaning and purpose of the code. Comments should be clear, concise, and in sync with the code.
  • Single line comment: Use // to comment the entire line.
  • Multi-line comments: Use /* */ to comment multi-line content. For comments on functions and classes, it is recommended to use the form of documentation blocks.

Example:

// 这是一个单行注释

/*
这是一个
多行注释
*/

/**
 * 这是一个函数的注释
 *
 * @param int $param1 参数1的描述
 * @param string $param2 参数2的描述
 * @return int 返回值的描述
 */
function myFunction($param1, $param2) {
    // code here
}

  1. Exception handling
    Good exception handling can increase the robustness and maintainability of the code. It is recommended to use try-catch blocks to catch and handle exceptions, and use custom exception classes to provide more detailed error information.

Example:

class MyException extends Exception {
    public function __construct($message, $code, Exception $previous = null) {
        parent::__construct($message, $code, $previous);
        // code here
    }
}

try {
    // code here
} catch (MyException $e) {
    // handle exception
} catch (Exception $e) {
    // handle other exceptions
}

  1. Focus on code reuse
    Code reuse is one of the important methods to improve development efficiency and code quality. Reduce redundant code and improve code maintainability by creating reusable functions, classes, or libraries.

Example:

function calculateDiscount($price, $discountRate) {
    // code here
    return $discountedPrice;
}

$price1 = 1000;
$discountRate = 0.1;
$discountedPrice1 = calculateDiscount($price1, $discountRate);

$price2 = 2000;
$discountRate = 0.2;
$discountedPrice2 = calculateDiscount($price2, $discountRate);
Copy after login

Conclusion:
By standardizing PHP writing, we can achieve an efficient and clear code style and improve the readability and maintainability of the code. In actual development, we should combine specific project needs and team collaboration to formulate coding standards suitable for our own team, and strictly abide by them. This will not only improve our individual development efficiency, but also help improve the collaborative development capabilities of the entire team.
