What are some best practices for naming superglobal arrays and function names in PHP?

When naming superglobal arrays and function names in PHP, it is important to follow naming conventions to ensure clarity and readability in your code. Use descriptive names that clearly indicate the purpose of the array or function. Avoid using vague or generic names that could lead to confusion or conflicts with built-in PHP functions or variables.

// Naming superglobal arrays:
$_GET - Use this array for accessing data sent via HTTP GET method.
$_POST - Use this array for accessing data sent via HTTP POST method.
$_SESSION - Use this array for storing session variables.

// Naming function names:
function calculateTotal() {
    // Function to calculate total
}

function getUserDetails() {
    // Function to get user details
}

function validateInput() {
    // Function to validate input
}
