范例

Example #1 面向对象风格

<?php
/* Open a connection */
$maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB");

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

$query = "SELECT name, zip FROM hotel.city ORDER BY name";
if ($stmt = $maxdb->prepare($query)) {

   /* execute query */
   $stmt->execute();

   /* store result */
   $stmt->store_result();

   printf("Number of rows: %d.\n", $stmt->num_rows);

   /* free result */
   $stmt->free_result();

   /* close statement */
   $stmt->close();
}

/* close connection */
$maxdb->close();
?>

Example #2 过程化风格

<?php
/* Open a connection */
$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");

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

$query = "SELECT name, zip FROM hotel.city ORDER BY name";
if ($stmt = maxdb_prepare($link, $query)) {

   /* execute query */
   maxdb_stmt_execute($stmt);

   /* store result */
   maxdb_stmt_store_result($stmt);

   printf("Number of rows: %d.\n", maxdb_stmt_num_rows($stmt));

   /* free result */
   maxdb_stmt_free_result($stmt);

   /* close statement */
   maxdb_stmt_close($stmt);
}

/* close connection */
maxdb_close($link);
?>

以上例程的输出类似于：
