I want to check specific drivers installed or not in a client's computer through the PHP, Is it possible with the PHP programming?
If it's possible, How can I do?

There is no general interface for this indeed, as PHP is a server side language, and you want to find out things on the client side. The only possibility is to either have a client side installable extension or alter the drive to expose itself through some kind of browser interface if you have control over the driver.

I've been reading about PHP document in https://www.php.net/manual/en/features.commandline.webserver.php and was wondering why built-in web server should not be used on a public network?
Is it because of the security issues?
If yes, is there any example or details about this?
From the documentation:
The web server runs only one single-threaded process, so PHP
applications will stall if a request is blocked.
Also, it won't restart by itself if for a reason or another the process crashes.
In a pinch, it's a good tool, but it's definitely not be used on a public network.

I was thinking is there a method to gain access to a client PC's SQL database? I am creating a web portal for our LAN clients and I will need to manipulate data on the client's database.
No. you cannot do this with PHP. Php runs on the server.
You cannot do this with javascript in the browser as it is not allowed access to the client pc.
You may be able to write a chrome or firefox plugin that will have access to the host pc and then write code to interact with it.
Or just write an application for your clients to install that comunicates with your app on the php server.

I use DB on regular basis to host static sites for clients so that it makes easy to change anything and ask to client check. I use 'Public' folder to do that. Colloboration with client becomes super fast and easy.
Now I researched a lot on google on hosting php site there. But didn't found anything. I need to upload small changes to server to show client and the process is again and again.
What you guys recommend as a good solution?
Set up some automatic deployment to a server that your client can access. Use version control for your changes. When you merge into a specific branch, your script can automatically do the deployment for you.

I recently went through an article which states the different combination to make an Web-Application , so I was wondering that when a developer should go for
1.php
2.asp
3.jsp/Servelets
anything on it would be appreciated
Developer should develop in which language he/she is comfortable.and client's requirement is also taken care of.
Open source web application should develop in PHP. Application meant to run in Windows server must develop in asp and in both the cases you can use java. Java is mostly use to develop desktop applications.
