Are there any alternative methods or libraries that can be used for password strength testing in PHP if Cracklib integration is problematic?

Cracklib integration for password strength testing in PHP can be problematic due to compatibility issues or difficulty in setting up the library. An alternative method is to use the zxcvbn library, which is a password strength estimator developed by Dropbox. This library can be easily integrated into PHP applications to provide accurate password strength testing without the need for external dependencies like Cracklib.

// Include the zxcvbn library
require_once 'path/to/zxcvbn.php';

// Password to test
$password = 'MySecurePassword123';

// Estimate password strength
$strength = zxcvbn($password);

// Output the password strength score
echo 'Password strength score: ' . $strength['score'];
