范例

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 * FROM dual" ;

 
 if ( $maxdb -> multi_query ( $query )) {
   do {
        
        if ( $result  =  $maxdb -> store_result ()) {
           while ( $row  =  $result -> fetch_row ()) {
                printf ( "%s\n" ,  $row [ 0 ]);
           }
            $result -> close ();
       }
        
        if ( $maxdb -> more_results ()) {
            printf ( "-----------------\n" );
       }
   } while ( $maxdb -> next_result ());
}

 
 $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 ());
   exit();
}

 $query  =  "SELECT * FROM dual" ;

 
 if ( maxdb_multi_query ( $link ,  $query )) {
   do {
        
        if ( $result  =  maxdb_store_result ( $link )) {
           while ( $row  =  maxdb_fetch_row ( $result )) {
                printf ( "%s\n" ,  $row [ 0 ]);
           }
            maxdb_free_result ( $result );
       }
        
        if ( maxdb_more_results ( $link )) {
            printf ( "-----------------\n" );
       }
   } while ( maxdb_next_result ( $link ));
}

 
 maxdb_close ( $link );
 ?>
