How to avoid ambiguity in PHP function naming?

Avoid ambiguity in PHP function naming by following these best practices: Use descriptive names that clearly express function functionality. Avoid abbreviations to improve readability. Keep the name simple and easy to understand and read. Avoid duplicate names to prevent conflicts. Use naming conventions to improve code readability.

How to avoid ambiguity in PHP function naming

Avoiding ambiguity in function naming is essential for writing readable and maintainable code. It's important. Following some best practices can help you make your code more understandable and reduce errors.

1. Use descriptive names

The function name should describe what the function performs. For example, a function that calculates the length of a string might be named calculate_string_length.

2. Avoid using abbreviations

Abbreviations can be difficult to understand, especially for people who are not familiar with code. For example, find_the_greatest_common_divisor is more descriptive than gcd.

3. Keep names simple

Function names should be long enough to make their purpose clear, but short enough to be easy to read. For example, calculate_the_product_of_two_numbers is better than calculate_the_product_of_two_numbers_and_return_the_result.

4. Avoid duplicate names

Using the same name in the same namespace may cause conflicts. Make sure that each function's name is unique within the scope.

5. Use naming conventions

Following a consistent naming convention can improve the readability of your code. For example, you can use the prefix get_ for functions that return a value, and the prefix set_ for functions that set a value.

Practical Case

Suppose we have two functions, one that calculates the sum of two numbers and the other that calculates the product of two numbers. Using the above best practices, we can name our functions like this:

// 计算两个数字的总和
function sum_two_numbers(int $num1, int $num2): int
{
    return $num1 + $num2;
}

// 计算两个数字的积
function multiply_two_numbers(int $num1, int $num2): int
{
    return $num1 * $num2;
}

These function names are descriptive and short, and follow consistent naming conventions. They are not ambiguous even if they are used in the same namespace.
