How to Create a PHP Database Connection Test Script to Check the Database Server Reachability

Many PHP applications need to access a database server and execute SQL queries to store and retrieve data in database table records.

If for some reason, the database server is not available for connection, any queries that the applications need to execute will fail with an error that may not be very clear what is the real cause.

This package provides a simple solution to check the availability of the database server.

It executes a dummy SQL query that is not useful for storing and retrieving data from the database server.

It only serves the purpose of checking if the database server is accessible.
