Someone just reinvented the equality operator with extra steps. The ifBothCorrect function literally just checks if two values are equal, but instead of using === or == , they wrote an entire function that assigns them to variables, compares them, and returns true or false. It's like using a forklift to pick up a pencil. But wait, there's more! The authentication logic fetches ALL usernames and ALL passwords from the database, then loops through them in nested foreach loops to validate credentials. That's O(n²) complexity for what should be a single database query. Your database is crying. Your security team is crying. I'm crying. The cherry on top? They're storing passwords in plain text (look at that getAllPasswords() call). This code is a security audit's final boss. It's so beautifully terrible that it almost feels like performance art.
