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