Get records from mySQL using PHP and send it to VB.net

I have a开发者_C百科 PHP script which accepts an argument and adds record in the mySQL database if its not available and if its already available it gives a message 'Record already found'.

How can i read this message from vb.net and do appropriate action such as

if data_is_in_db then msgbos("your record already found in the database")

if data_is_not_in_db then msgbox("your record has been added in the database")

Please help me for this, as i am a newbie.

Thanks

It would be simpler to integrate a database connection inside your VB.NET application instead of trying to communicate with a PHP script. Just my two cents.

You can (amongst many other possibilities) use the http status message for that.

E.g send a 201 Created when the record has been added and a 409 Conflict if the record is already there.
