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();
}


$charset  $maxdb -> character_set_name ();
printf  ( "Current character set is %s\n" $charset );

$maxdb -> close ();
?>

Example #2 过程化风格

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


if (! $link ) {
   
printf ( "Connect failed: %s\n" maxdb_connect_error ());
   exit();
}


$charset  maxdb_character_set_name ( $link );
printf  ( "Current character set is %s\n" , $charset );


maxdb_close ( $link );
?>

以上例程的输出类似于:

Current character set is ascii
