Example #1 面向对象风格

  <?php
$maxdb  = new  maxdb ( "localhost" ,  "MONA" ,  "RED" ,  "DEMODB" );

 
 if ( maxdb_connect_errno ()) {
    printf ( "Connect failed: %s\n" ,  maxdb_connect_error ());
   exit();
}

 $query  =  "SELECT name, state FROM hotel.city ORDER by zip" ;

if ( $result  =  $maxdb -> query ( $query )) {

    
    while ( $obj  =  $result -> fetch_object ()) {
        printf  ( "%s (%s)\n" ,  $obj -> NAME ,  $obj -> STATE );
   }

    
    $result -> close ();
}

 
 $maxdb -> close ();
 ?>

Example #2 过程化风格

  <?php
$link  =  maxdb_connect ( "localhost" ,  "MONA" ,  "RED" ,  "DEMODB" );

 
 if ( maxdb_connect_errno ()) {
    printf ( "Connect failed: %s\n" ,  maxdb_connect_error ());
