SYNOPSIS
Warning
This extension is deprecated as of PHP 5.5.0, and will be removed in the future. Instead, the MySQLi or PDO_MySQL extension should
be used. See also MySQL: choosing an API guide and related FAQ for more information. Alternatives to this function include:
omysqli_get_proto_info(3)
int mysql_get_proto_info ([resource $link_identifier = NULL])
DESCRIPTION
Retrieves the MySQL protocol.
o $
link_identifier -The MySQL connection. If the link identifier is not specified, the last link opened by mysql_connect(3) is
assumed. If no such link is found, it will try to create one as if mysql_connect(3) was called with no arguments. If no connection
is found or established, an E_WARNING level error is generated.
Returns the MySQL protocol on success or FALSE on failure.

$link = mysql_connect('localhost', 'mysql_user', 'mysql_password');
if (!$link) {
die('Could not connect: ' . mysql_error());
}
printf("MySQL protocol version: %s
", mysql_get_proto_info());
?>
The above example will output something similar to:
MySQL protocol version: 10
mysql_get_client_info(3), mysql_get_host_info(3), mysql_get_server_info(3).
