in PHP is it possible to create virtual number functionality to send and receive text messages in the database for web based applications?
Not with PHP by itself, no. Sending text messages requires access to the mobile telephone system network, which is a separate network from the Internet. To send text messages from a web server, you would need to use some sort of third-party bridging service that would receive a message sent from your web server, translate it into a text message, and send it out over the mobile phone network.
Hey
@Sesquipedalian Thank you so much for your guidance. as you said I have chosen a third party messaging api (http://textdrip.com/) bridging service. do you have any hand on experience in integrating thirdparty API in databases?
I do, but it would be a more than trivial amount of work. You should ask in the Help Wanted (https://www.simplemachines.org/community/index.php?board=50.0) board. You can probably find someone to hire to do this for you. I'm not available.
