What considerations should be made when balancing complexity and readability in generated passwords using PHP?

When balancing complexity and readability in generated passwords using PHP, it is important to consider the balance between creating strong, secure passwords and ensuring they are user-friendly and easy to remember. One approach is to use a mix of uppercase and lowercase letters, numbers, and special characters to increase complexity, while also avoiding ambiguous characters that can be easily confused. Additionally, consider the length of the password and whether it meets any specific requirements for the system it will be used in. 

function generatePassword($length = 12) {
    $chars = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789!@#$%^&*()_+';
    $password = '';
    
    for ($i = 0; $i < $length; $i++) {
        $password .= $chars[rand(0, strlen($chars) - 1)];
    }
    
    return $password;
}

echo generatePassword();
