Get MySQL protocol info (PHP 4 >= 4.0.5, PHP 5, PECL mysql:1.0)
int mysql_get_proto_info ( [resource link_identifier] )

Retrieves the MySQL protocol.



The MySQL connection. If the link identifier is not specified, the last link opened by mysql_connect() is assumed. If no such link is found, it will try to create one as if mysql_connect() was called with no arguments. If by chance no connection is found or established, an E_WARNING level warning is generated.

Return Values

Returns the MySQL protocol on success, or FALSE on failure.


Example 1444. mysql_get_proto_info() example

= mysql_connect('localhost', 'mysql_user', 'mysql_password');
if (!
$link) {
'Could not connect: ' . mysql_error());
printf("MySQL protocol version: %s\n", mysql_get_proto_info());

The above example will output something similar to:

MySQL protocol version: 10
