In PHP, how do I validate objects in vanilla PHP?

In vanilla PHP, validating objects is crucial to ensure that they meet specific criteria before using them within your application. This can involve checking for mandatory properties, ensuring correct data types, and validating values based on criteria such as format or range. Below is an example of how you can validate objects in PHP.


        <?php
        class User {
            public $name;
            public $email;

            public function __construct($name, $email) {
                $this->name = $name;
                $this->email = $email;
            }

            public function validate() {
                $errors = [];

                // Check if name is provided
                if (empty($this->name)) {
                    $errors[] = "Name is required.";
                }

                // Validate email format
                if (!filter_var($this->email, FILTER_VALIDATE_EMAIL)) {
                    $errors[] = "Invalid email format.";
                }

                return $errors;
            }
        }

        $user = new User("", "invalid-email");
        $validationErrors = $user->validate();

        if (empty($validationErrors)) {
            echo "User is valid.";
        } else {
            echo "Validation errors: " . implode(", ", $validationErrors);
        }
        ?>
