Are there potential pitfalls in using prefixes like "fk_" to identify foreign key fields in PHP functions?

Using prefixes like "fk_" to identify foreign key fields in PHP functions can potentially lead to confusion and inconsistency in the codebase. It is better to use more descriptive and meaningful names for foreign key fields to improve code readability and maintainability. By using clear and consistent naming conventions, developers can easily understand the purpose of each field without relying on prefixes.

// Incorrect usage of prefix "fk_" for foreign key field
function getUserInfo($fk_user_id) {
    // Function logic
}

// Correct usage of descriptive name for foreign key field
function getUserInfo($user_id) {
    // Function logic
}
