Common types of errors in PHP function naming

Naming conventions are key to building robust and easy-to-maintain PHP code. Wrongly named functions can make code difficult to understand and maintain, leading to errors and confusion. Common types of PHP function naming errors include:

• Using non-descriptive names: For example, naming a function f or func does not convey its purpose.
• Use ambiguous names: For example, check_input does not explicitly specify which aspect of the input it checks.
• Using abbreviations or slang : For example, calc_tot or findMe can make the purpose of a function difficult to understand.
• Using underscores or hyphens : For example, function_name or function-name violates PHP naming conventions.
• Use inconsistent case : For example, getPhoneNumber and getPhoneNum can cause confusion.

Practical case

The following example shows incorrect function naming:

// 错误的命名：不描述性
function f($a, $b) {
  return $a + $b;
}

// 错误的命名：模糊不清
function check_input($input) {
  // 检查输入的多个方面
}

// 错误的命名：使用缩写
function calc_tot($items) {
  return array_sum($items);
}

// 错误的命名：使用下划线
function get_phone_number($user) {
  return $user->phone_number;
}

// 错误的命名：不一致的大小写
function GetPhoneNumber($user) {
  return $user->phone_number;
}

Correct function naming

Correct function naming should be clear, Be concise and accurately describe the behavior of the function. The following guidelines can be used to create good function names:

• Use a verb to start the function name.
• Use descriptors to specify the function of the function.
• Use camel spelling, with the first letter of each word capitalized.
• Avoid abbreviations, slang, and underscores.
• Make sure function names are unique within the code base.
