Another way to Retrieve MySQL Server version by using $wpdb:
```
global $wpdb;
$db_version_dump = $wpdb->get_var( 'SELECT VERSION() AS version from DUAL' );
if ( preg_match( '/\d+(?:\.\d+)+/', $db_version_dump, $matches ) ) {
    echo $matches[0]; //returning the first match of Database Version
}
```
