How can database redundancy be minimized in PHP applications to optimize performance and storage?

Database redundancy can be minimized in PHP applications by implementing efficient database normalization techniques, using indexes appropriately, and avoiding duplicate data storage. By structuring the database tables properly and avoiding redundant data, the performance and storage efficiency can be optimized. 

// Example of implementing database normalization in PHP using PDO:

// Connect to the database
$pdo = new PDO('mysql:host=localhost;dbname=mydatabase', 'username', 'password');

// Create a table for users
$pdo->query("CREATE TABLE users (
    id INT(11) AUTO_INCREMENT PRIMARY KEY,
    username VARCHAR(50) NOT NULL,
    email VARCHAR(50) NOT NULL UNIQUE,
    password VARCHAR(255) NOT NULL
)");

// Create a table for user profiles
$pdo->query("CREATE TABLE profiles (
    id INT(11) AUTO_INCREMENT PRIMARY KEY,
    user_id INT(11) NOT NULL,
    first_name VARCHAR(50) NOT NULL,
    last_name VARCHAR(50) NOT NULL,
    bio TEXT,
    FOREIGN KEY (user_id) REFERENCES users(id)
)");
