PHP framework i TDD... Kad?

[Ivan988]

Ne ne, ali meni su za jedan posao trazili CI, pa sam resio da prvo njega naucim.

Poceo sam da pisem jednu klasu (moju prvu klasu, zato budite nezni ), tek sam poceo sa njom, tako da imam jos par metoda da dodam i nesto da popravim.

PHP kôd:

<?php

/**
 * Users

 * Class for registering new users

 */
class Users {
    
    protected $conn;    //db connection
    protected $formStatus; //status of form inputs
    protected $tableName; //name of db table where 
    
    
    /**

        try

            $this->tableName = $tableName;
            $this->conn = new PDO("mysql:host={$host};dbname={$db}", $user, $pass);
            $this->conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
        }

        public function createNewUser($userName, $password,$repPassword, $email)

                echo "Success<br /><a href='signUp.php'>Back</a>";
                
            } 
            catch(Exception $e)
            {
                echo $e->getMessage();
                echo "<a href='signUp.php'>Back</a> ";
