What is the purpose of using openssl_random_pseudo_bytes in PHP for generating secure passwords?

When generating secure passwords in PHP, it is important to use a cryptographically secure method to ensure the randomness and unpredictability of the generated passwords. The function openssl_random_pseudo_bytes in PHP is specifically designed for this purpose, as it generates cryptographically secure pseudo-random bytes that can be used to create strong passwords.

$length = 12; // desired length of the password
$password = bin2hex(openssl_random_pseudo_bytes($length));
echo $password;
