 * How do connect to the database because of MySQL extension not available in the
   latest PHP version using WordPress.
 * current WordPress using
 * function create_js_html_page() {
 *  $result = mysql_query(“SELECT DATABASE()”) or die(mysql_error());
    $dbselect
   = mysql_result($r,0); echo $dbselect;
 * }
 * anybody know how to replace mysql_query to other code because i’m try using mysqli
   not working. i just want call database name.

 * What exactly are you trying to do? I recommend using wpdb instead of direct mysql
   queries. See: [https://developer.wordpress.org/reference/classes/wpdb/](https://developer.wordpress.org/reference/classes/wpdb/).

 * You do not need to connect to get the name of WP’s database.
    `echo DB_NAME;`

 * Heh, I figured there was more to your story. Like csloisel said, use the wpdb
   class like WP does. WP creates a global instance of wpdb to connect with its 
   DB. Create your own instance for your own connection. Then you can use most of
   the wpdb methods and properties, except for WP specific properties like wpdb::
   options of course.
