使用PHP在服务器上编译C代码

Question

I have this php code

<?php
 $Command = "cd /var/www/html/Codiad/workspace/workspace  2>&1; gcc HelloWorld.c; ./a.out"
 $Method1 = exec($Command);
 echo $Method1;
?>

The code works fine, it shows the output, but I want only see the output after click on a button. How can I do that remaining on the same page? To be more precise I have two buttons, one for compiling code and one for execute it.

Answer 1

I suggest you do it with AJAX and make 2 calls. One button clicks makes request that will compile. Other will execute the code.
