How can the use of "goto" affect the readability and maintainability of PHP code?

The use of "goto" in PHP can make the code harder to read and maintain because it can create spaghetti code that is difficult to follow. Instead of using "goto", it is recommended to refactor the code into smaller, more manageable functions or use control structures like loops and conditional statements to achieve the desired logic. 

// Example of refactoring code without using "goto"
function processUserData($userData) {
    if ($userData['is_valid']) {
        // Process valid user data
    } else {
        // Handle invalid user data
    }
}
