Example

例 1072. Object oriented style

<?php
$maxdb
= new maxdb("localhost", "MONA", "RED", "DEMODB");

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

if (
$stmt = $maxdb->prepare("SELECT name FROM hotel.city WHERE name=? OR state=?")) {

 
$marker = $stmt->param_count;
 
printf("Statement has %d markers.\n", $marker);

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

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

例 1073. Procedural style

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

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

if (
$stmt = maxdb_prepare($link, "SELECT name FROM hotel.city WHERE name=? OR state=?")) {

 
$marker = maxdb_stmt_param_count($stmt);
 
printf("Statement has %d markers.\n", $marker);

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

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

The above examples would produce the following output:

Statement has 2 markers.
