Following on from Jeremy S's example. 
Instead of defining LDAP_OPT_DIAGNOSTIC_MESSAGE as 0x32 then using it, you can just use the option already defined as that value :)

LDAP_OPT_ERROR_STRING

Here is how to tell if an Active Directory user account expired:

define('LDAP_OPT_DIAGNOSTIC_MESSAGE', 0x0032);

ldap_set_option($conn, LDAP_OPT_PROTOCOL_VERSION, 3);
ldap_set_option($conn, LDAP_OPT_REFERRALS, 0);

$bind = ldap_bind($conn, $user, $pass);

ldap_get_option($conn, LDAP_OPT_DIAGNOSTIC_MESSAGE, $extended_error);

if (!empty($extended_error))
{
    $errno = explode(',', $extended_error)[2];
    $errno = explode(' ', $errno)[2];
    $errno = intval($errno);

    if ($errno == 532)
        $err = 'Unable to login: Password expired.';
}

PHP 7.1 added support for configuring the LDAP CA/Cert environment directly, rather than relying on the environment variables. I noticed that a lot of people are having trouble getting this to work.

The correct way is:
$ds=ldap_connect("ldap.google.com");  
ldap_set_option(NULL, LDAP_OPT_X_TLS_CERTFILE, "/path/file.crt");
ldap_set_option(NULL, LDAP_OPT_X_TLS_KEYFILE, "/path/file.key");
ldap_set_option($ds, LDAP_OPT_PROTOCOL_VERSION, 3);
ldap_set_option($ds, LDAP_OPT_REFERRALS, 0);
ldap_start_tls($ds);
...
ldap_close($ds);
