范例
Example #1 面向对象风格
<?php
$maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB");
/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s\n", maxdb_connect_error());
exit();
}
$query = "SELECT * FROM dual";
/* execute multi query */
if ($maxdb->multi_query($query)) {
do {
/* store first result set */
if ($result = $maxdb->store_result()) {
while ($row = $result->fetch_row()) {
printf("%s\n", $row[0]);
}
$result->close();
}
/* print divider */
if ($maxdb->more_results()) {
printf("-----------------\n");
}
} while ($maxdb->next_result());
}
/* close connection */
$maxdb->close();
?>
Example #2 过程化风格
<?php
$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");
/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s\n", maxdb_connect_error());
exit();
}
$query = "SELECT * FROM dual";
/* execute multi query */
if (maxdb_multi_query($link, $query)) {
do {
/* store first result set */
if ($result = maxdb_store_result($link)) {
while ($row = maxdb_fetch_row($result)) {
printf("%s\n", $row[0]);
}
maxdb_free_result($result);
}
/* print divider */
if (maxdb_more_results($link)) {
printf("-----------------\n");
}
} while (maxdb_next_result($link));
}
/* close connection */
maxdb_close($link);
?>
