(PECL maxdb >= 1.0)
maxdb_get_proto_info -- maxdb->protocol_version — Returns the version of the MaxDB protocol used
Procedural style:
Object oriented style (property):
Returns an integer representing the MaxDB protocol version used by the connection represented by the link parameter.
Returns an integer representing the protocol version (constant 10).
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();
}
/* print protocol version */
printf("Protocol version: %d\n", $maxdb->protocol_version);
/* close connection */
$maxdb->close();
?>
Example #2 Procedural style
<?php
$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");
/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s\n", maxdb_connect_error());
exit();
}
/* print protocol version */
printf("Protocol version: %d\n", maxdb_get_proto_info($link));
/* close connection */
maxdb_close($link);
?>
上例的输出类似于：
Protocol version: 10
