What are some common pitfalls to avoid when implementing a multi-level referral system in PHP?

One common pitfall to avoid when implementing a multi-level referral system in PHP is not properly tracking and managing the referral relationships between users. To solve this issue, ensure that each user's referral information is stored in a database table that includes fields for the user's ID, their referrer's ID, and the level of the referral. 

// Example database table structure for tracking referral relationships
CREATE TABLE referrals (
    id INT AUTO_INCREMENT PRIMARY KEY,
    user_id INT NOT NULL,
    referrer_id INT NOT NULL,
    level INT NOT NULL
);
