Object oriented style (method):
maxdb
bool ping

)

예제
Example#1 Object oriented style
<?php
$maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB");
/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s\n", maxdb_connect_error());
exit();
}
/* check if server is alive */
if ($maxdb->ping()) {
printf ("Our connection is ok!\n");
} else {
printf ("Error: %s\n", $maxdb->error);
}
/* close connection */
$maxdb->close();
?>
Example#2 Procedural style
<?php
$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");
/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s\n", maxdb_connect_error());
exit();
}
/* check if server is alive */
if (maxdb_ping($link)) {
printf ("Our connection is ok!\n");
} else {
printf ("Error: %s\n", maxdb_error($link));
}
/* close connection */
maxdb_close($link);
?>
The above examples would produce the following output:
Our connection is ok!
