Can a MySQL Trigger Execute a PHP Script?

Invoking a PHP Script from Within a MySQL Trigger

Background:

You're tasked with implementing a solution that initiates a PHP function upon record insertion into a MySQL database table. However, the record insertion process is beyond your control. The question arises: Can a MySQL trigger mechanism trigger PHP script invocation?

Answer:

The crux of this challenge lies in the separation of the MySQL and PHP environments. MySQL triggers are executed on the MySQL server, while PHP scripts run on the PHP server.

Limitations:

Directly invoking PHP scripts from within MySQL triggers may not be possible due to their distinct execution environments.

Potential Solution (UDF)

One possible workaround involves creating a MySQL User-Defined Function (UDF) that calls an external application. For instance, you can employ the sys_exec() UDF to launch the PHP executable or script. While this approach is not straightforward, it offers a feasible solution.
