Creating a remote compilation system

Question

PHP

What technologies are used to create a subject? This refers to systems similar to those used in sports programming: a person uploads his code, specifies the language, the code is sent to the server, compiled there, and the compiler's response is returned. What can be read on this topic? What technology should be used? Are there ready-made open source solutions?

Answer 1

If we are talking about compilation, without running, then something like this?

<?
$commands = [
    'ls'    => 'ls -la', 
    'basic' => '/path/to/basic param1 param2', 
    'java'  => '/path/to/java param param',
];

if (isset($_FILES['file']) && !$_FILES['file']['error'] && isset($commands[$_POST['lang']]))
{
    $comm = $commands[$_POST['lang']];
    $file = $_FILES['file']['tmp_name'];

    echo "<pre>";
    echo `$comm $file 2>&1`;
    echo "</pre>";
}
?>
<form enctype="multipart/form-data" method="POST">
  <select name="lang">
  <?php foreach ($commands as $key => $void):?>
    <option><?=$key?></option>
  <?php endforeach ?>
  </select><input name="file" type="file" /><input type="submit" /></form>

Answer 2

Maybe distcc will work?
