execute c compiler from Php page

[pascal2020]

Hi everyone,
I'm doing a website to collect C scripts. Pages allow to upload users' pages and get compiler feedback. I would know how to install C compiler not as standalone application but rather directly into web server.
Thank you

I have no idea what you mean by that. What is "not a standalone app" and what is meant by "directly into web server". Anyway, there is NO WAY to configure Apache to compile C programs. Apache is not a Compiler. C programs need a C compiler, which of course is a "standalone"(?) application.

On the other hand, there is no problem to invoke a C compiler from Apache and/or from PHP scripts. Therefore i struggle to understand, what you are meaning.

https://repl.it/languages/c seems to do what you want. It is up to you, to finde someone that maybe released such a software as opensource.
It should also be running in a good sandbox.
I only know it for typesetting of TeX-Documents as https://katex.org/.

Thank you Nobbie,
At the moment my site works properly. I installed on my pc Xampp, to manage my pages, and MinGW to allow executing GCC. My database collect any user C script file and compiler feedback. Well, I would try to do the same things without calling GCC, for example I would like know If exists a C compiler plugin for Xampp. I hope to have explained myself well. Have a nice day

Thank you Nemesis for the good advice. I'll see it in the afternoon

I would like know If exists a C compiler plugin for Xampp.

What is a "plugin for Xampp"? Xampp is not a software, its only a name for a distribution. And there are no "plugins" anyway. There are extensions for PHP and modules for Apache and engines for MySQL, but there is no such a huge thing like a C compiler? That request is still a little bit weird.

Of course you can implement a CGI script which is invoked to run on C-source and which triggers the C-Compiler, but that is a question of Apache configuration and/or creating some basic CGI scripts. Still, the C-Compiler itself will be gcc or similar, there is no builtin C-Compiler in Apache or so.
