These conventions improve code readability, maintainability, and teamwork efficiency.

PHP function naming convention

In PHP, following specific function naming conventions is important for code readability and maintainability Sex is crucial. These conventions help team members and maintainers quickly and easily understand the purpose and use of functions.

Convention

• Lowercase camel case nomenclature: Use lowercase letters for function names, with the first letter of each word capitalized. For example: createOrder, getUserById.
• Verb or gerund: The function name uses a verb or gerund to describe its operation. For example: saveOrder, getAccountBalance.

function create_order($customer_id, $product_ids) {
    // 创建订单并返回订单 ID
}

This function does not follow the naming convention because it uses underscores, And not in verb form. The improved version is as follows:

function createOrder($customerId, $productIds) {
    // 创建订单并返回订单 ID
}

Benefits

Following the function naming convention provides the following benefits:

• Readability And understandability: Consistent function naming makes code easier to read and understand.
• Code maintainability: Easier to identify and update functions.
• Teamwork: Enforcing conventions on coding teams helps reduce coding style conflicts.
