PHP function naming convention: Use camel case naming: getPhoneNumber(), createUser() Length is concise: generally no more than 30 characters Use verbs: getData(), createUser(), validateInput() Avoid common terms: process( ), handle() use prefix/suffix: isValidateInput(), setUserInfo()
In In PHP, function naming conventions are key to ensuring code readability and maintainability. Following consistent naming conventions helps developers quickly understand the purpose and usage of code. This article will introduce the naming convention of PHP functions and illustrate it through practical cases.
PHP function name must start with a letter, underscore or backslash, and can be followed by numbers, letters or underscores. Function names are case-sensitive.
It is recommended to use "camel case naming":
getPhoneNumber()
, createUser()
The function name should be concise and to the point , reflecting the main purpose of the function. It is generally recommended not to exceed 30 characters.
Function names should use verbs to describe their operations. For example:
getData()
createUser()
validateInput()
Do not use things like process()
, handle()
, etc. Generic terms as function names. These terms are too vague to understand what the function does.
To enhance readability, you can use prefixes or suffixes to indicate functions of a specific type or purpose. For example:
is
or validate
get
set
_private
Example 1: Get the user name
function getUserName(int $userId) : string { // 代码逻辑 }
The function name follows the camel case naming method and starts with the verb get
, which clearly indicates its purpose of getting the user name.
Example 2: Validate input data
function validateInputData(array $data) : bool { // 代码逻辑 }
The function name uses the suffix _private
to indicate that this is a private function, and uses the prefix validate
indicates its main purpose.
Following the PHP function naming convention helps improve the readability and maintainability of the code. By using camelCase, appropriate verbs, and prefixes/suffixes, you can create clear, easy-to-understand functions.
