How can I optimize the PHP code to improve performance and readability?

To optimize PHP code for performance and readability, consider using proper coding standards, avoiding unnecessary loops and function calls, and optimizing database queries. Additionally, caching data where possible can also improve performance. Example: 

// Avoid unnecessary loops and function calls
$sum = 0;
for ($i = 1; $i <= 1000; $i++) {
    $sum += $i;
}

// Optimize database queries
$query = "SELECT * FROM users WHERE status = 'active'";
$result = $pdo->query($query);

// Implement proper coding standards
class User {
    private $name;
    
    public function __construct($name) {
        $this->name = $name;
    }
    
    public function getName() {
        return $this->name;
    }
}
