How can PHP developers implement password generation functionality that balances security and user-friendliness, considering factors like password complexity requirements and ease of memorization?

To implement password generation functionality that balances security and user-friendliness, PHP developers can create a function that generates random passwords with a mix of uppercase and lowercase letters, numbers, and special characters. Additionally, developers can provide options for users to choose the length and complexity of the generated password. This approach ensures strong passwords while still being manageable for users to remember. 

function generatePassword($length = 12, $complexity = 'medium') {
    $uppercase = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ';
    $lowercase = 'abcdefghijklmnopqrstuvwxyz';
    $numbers = '0123456789';
    $specialChars = '!@#$%^&*()-_+=';
    
    $chars = '';
    
    switch($complexity) {
        case 'low':
            $chars = $lowercase . $numbers;
            break;
        case 'medium':
            $chars = $uppercase . $lowercase . $numbers;
            break;
        case 'high':
            $chars = $uppercase . $lowercase . $numbers . $specialChars;
            break;
        default:
            $chars = $uppercase . $lowercase . $numbers;
            break;
    }
    
    $password = '';
    
    for ($i = 0; $i < $length; $i++) {
        $password .= $chars[rand(0, strlen($chars) - 1)];
    }
    
    return $password;
}

// Usage
$password = generatePassword(12, 'high');
echo $password;
