 * hello there ,
    I have something that I just notice .. I know that wordpress uses
   the codes located in ‘**wp-config.php**‘ file , to connect to a specific database,,
   the codes for specifying the host , database , user and password : define(‘DB_NAME’,‘
   db’); define(‘DB_USER’, ‘user’); define(‘DB_PASSWORD’, ‘pass’); define(‘DB_HOST’,‘
   localhost’);
 * But I just notice something ,that when I use some mysql codes in a wordpress 
   site it doesn’t work because there is no connection to any server or any database.
   
   for example in **single.php** , Im using this code :
 *     ```
       $myrows = mysql_query("SELECT * FROM wp_slides_plugin WHERE slide_name='Main' ORDER BY position ASC"); // order by
   
       while($row= mysql_fetch_array($myrows)){
       $url[]=$row['url'];
       $title[]=$row['title'];
       $link[]=$row['link'];
       }
       ```
   
 * It doesnt work unless I connect the site with the database I use , so I have 
   to add the line :
    `mysql_query("use db", mysql_connect('localhost','user','pass'));`
 * so ,I have to connect to the database twice , its not enough to use the wordpress
   codes for connection !!
 * do I have to add mysql connection line every time I want to use mysql ?
    or there
   is some way to fix this problem ?
 * Note: This problem starts when I start using ‘**MySQL “Improved” extension**‘
   in order to use **MySQLi** on easyapache . everything was working normally with
   wordpress sites before enable ‘**MySQL “Improved” extension**‘ .
    and as you 
   can see , after enable that choice , all my wordpress sites stop reading the 
   connection codes of wordpress while using mysql codes .
 * Please help me if you can ..

 * WordPress has its own database functions to handle databases related works. Please
   us this: [https://codex.wordpress.org/Class_Reference/wpdb](https://codex.wordpress.org/Class_Reference/wpdb)
