The Note You're Voting On

I fiddled around with the internal webserver and had issues regarding handling static files, that do not contain a dot and a file extension.

The webserver responded with 200 without any content for files with URIs like "/testfile".

I am not certain if this is a bug, but I created a router.php that now does not use the "return false;" operation in order to pass thru the static file by the internal webserver.

Instead I use fpassthru() to do that.

In addition to that, my router.php can be configured to...
- ... have certain index files, when requesting a directory
- ... configure regex routes, so that, if the REQUEST_URI matches the regex, a certain file or directory is requested instead. (something you would do with nginx config or .htaccess ModRewrite)

Maybe someone finds this helpful.

================================

<?php

$indexFiles = ['index.html', 'index.php'];
$routes = [
  '^/api(/.*)?$' => '/index.php'
];

$requestedAbsoluteFile = dirname(__FILE__) . $_SERVER['REQUEST_URI'];

// check if the the request matches one of the defined routes
foreach ($routes as $regex => $fn)
{
  if (preg_match('%'.$regex.'%', $_SERVER['REQUEST_URI']))
  {
    $requestedAbsoluteFile = dirname(__FILE__) . $fn;
    break;
  }
}

// if request is a directory call check if index files exist
if (is_dir($requestedAbsoluteFile))
{
  foreach ($indexFiles as $filename)
  {
    $fn = $requestedAbsoluteFile.'/'.$filename;
    if (is_file($fn))
    {
      $requestedAbsoluteFile = $fn;
      break;
    }
  }
}

// if requested file does not exist or is directory => 404
if (!is_file($requestedAbsoluteFile))
{
  header($_SERVER['SERVER_PROTOCOL'].' 404 Not Found');
  printf('"%s" does not exist', $_SERVER['REQUEST_URI']);
  return true;
}

// if requested file is'nt a php file
if (!preg_match('/\.php$/', $requestedAbsoluteFile)) {
  header('Content-Type: '.mime_content_type($requestedAbsoluteFile));
  $fh = fopen($requestedAbsoluteFile, 'r');
  fpassthru($fh);
  fclose($fh);
  return true;
}

// if requested file is php, include it
include_once $requestedAbsoluteFile;
