Примеры
Пример #1 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();
}
$query = "SELECT name, cno from hotel.customer ORDER BY cno";
if ($result = $maxdb->query($query)) {
/* Get field information for all columns */
$finfo = $result->fetch_fields();
foreach ($finfo as $val) {
printf("Name: %s\n", $val->name);
printf("Table: %s\n", $val->table);
printf("max. Len: %d\n", $val->max_length);
printf("Flags: %d\n", $val->flags);
printf("Type: %d\n\n", $val->type);
}
$result->close();
}
/* close connection */
$maxdb->close();
?>
Пример #2 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();
}
$query = "SELECT name, cno from hotel.customer ORDER BY cno";
if ($result = maxdb_query($link, $query)) {
/* Get field information for all columns */
$finfo = maxdb_fetch_fields($result);
foreach ($finfo as $val) {
printf("Name: %s\n", $val->name);
printf("Table: %s\n", $val->table);
printf("max. Len: %d\n", $val->max_length);
printf("Flags: %d\n", $val->flags);
printf("Type: %d\n\n", $val->type);
}
maxdb_free_result($result);
}
/* close connection */
maxdb_close($link);
?>
Результатом выполнения данного примера будет что-то подобное:
Name: NAME Table: max. Len: 10 Flags: -1 Type: 2 Name: CNO Table: max. Len: 4 Flags: -1 Type: 0
