What are the benefits of modularizing PHP code for better organization and reusability in projects?

Modularizing PHP code helps in better organization and reusability by breaking down the code into smaller, manageable modules or components. This approach allows developers to isolate specific functionalities, making it easier to maintain and update the codebase. Additionally, modularization promotes code reusability, as modules can be easily reused in different parts of the project or in future projects.

// Example of modularized PHP code
// File: utils.php

function validateEmail($email) {
    return filter_var($email, FILTER_VALIDATE_EMAIL);
}

function sanitizeInput($input) {
    return htmlspecialchars($input);
}
