예제

Example #1 객체 기반 형식

<?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();

   
/* bind result variables */
   
$stmt->bind_result($name$code);

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

   
/* seek to row no. 5 */
   
$stmt->data_seek(5);

   
/* fetch values */
   
$stmt->fetch();

   
printf ("City: %s  Zip: %s\n"$name$code);

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

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

Example #2 절차식 형식

<?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);

   
/* bind result variables */
   
maxdb_stmt_bind_result($stmt$name$code);

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

   
/* seek to row no. 5 */
   
maxdb_stmt_data_seek($stmt5);

   
/* fetch values */
   
maxdb_stmt_fetch($stmt);

   
printf ("City: %s  Zip: %s\n"$name$code);

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

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