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();
}

 $maxdb -> query ( "CREATE TABLE temp.mycity LIKE hotel.city" );

 $city  =  "'s Hertogenbosch" ;

 
 if (! $maxdb -> query ( "INSERT into temp.mycity VALUES ('11111',' $city ','NY')" )) {
    printf ( "Error: %s\n" ,  $maxdb -> sqlstate );
}

 $city  =  $maxdb -> real_escape_string ( $city );

 
 if ( $maxdb -> query ( "INSERT into temp.mycity VALUES ('22222',' $city ','NY')" )) {
    printf ( "%d Row inserted.\n" ,  $maxdb -> affected_rows );
}

 $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();
}

 maxdb_query ( $link ,  "CREATE TABLE temp.mycity LIKE hotel.city" );

 $city  =  "'s Hertogenbosch" ;

 
 if (! maxdb_query ( $link ,  "INSERT into temp.mycity VALUES ('11111',' $city ','NY')" )) {
    printf ( "Error: %s\n" ,  maxdb_sqlstate ( $link ));
}

 $city  =  maxdb_real_escape_string ( $link ,  $city );

 
 if ( maxdb_query ( $link ,  "INSERT into temp.mycity VALUES ('22222',' $city ','NY')" )) {
    printf ( "%d Row inserted.\n" ,  maxdb_affected_rows ( $link ));
}

 maxdb_close ( $link );
 ?>

以上例程的输出类似于：
