PHP code for serial number help

[NikolaTesla]

I have a script using php to store serial numbers and credentials.

1 = invalid or unsuccessful
-1 = successful or valid

I am writing a script using PHP to get the serial number and credentials. My problem is have a user when they uninstall the program or software, they can't reuse their credentials and serial that was provided. I want to write a script that will allow a user after uninstalling the program to reuse their credentials and serial number to reinstall the program. I have a token system in my script that -1 equals successful serial number and 1 equals invalid credentials. How would I write script for this?

I have used the code already provided by your website. Really helpful.

Hi,

If you want to send some information to your server when a user uninstalls the product, you can add a "Send install information to your web server" custom action that will be executed only on uninstall.

Based on the information sent by this custom action, you can run a script that will make the appropriate changes to the information stored in your database.

Best regards,
