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:
Warning: maxdb_query(): -5016 POS(43) Missing delimiter: ) <...> Error: 42000 1 Row inserted.
