What are the best practices for naming functions in PHP to ensure clarity and maintainability?

When naming functions in PHP, it is important to use clear and descriptive names that accurately convey the purpose of the function. This helps other developers understand the functionality of the function without needing to dive into the implementation details. Additionally, following a consistent naming convention, such as using camelCase or snake_case, can improve maintainability and readability of the codebase.

// Example of clear and descriptive function naming in PHP
function calculateTotalPrice($items) {
    // Function logic here
}

function fetchUserData($userId) {
    // Function logic here
}
