Change detection in MySQL.
Hi,
I am trying to build a application in which I can be able to flow data to MySQL and vice -versa.
I need to understand that how the update, any changes done in MySQL database will be known or immediately flown to other side?
What is the Change detection mechanism in MySQL?
What I am trying to understood is :
If I add some entry in Database it has immediately flown to other side.
Can you please shed some light on this?

LEARN ABOUT PHP
mysql_get_proto_info
MYSQL_GET_PROTO_INFO(3) 1 MYSQL_GET_PROTO_INFO(3)
mysql_get_proto_info - Get MySQL protocol info
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.
Example #1
mysql_get_proto_info(3) example
<?php
$link = mysql_connect('localhost', 'mysql_user', 'mysql_password');
if (!$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).
