Little Utility to convert a directory of standalone php files into a Symfony controller class

merge_files.php

<?php
$targetDir = '../public/';
$output = "<?php\n";
$output .= "namespace App\Controller\n\n";
$output .= "#[Route('/')]\n";
$output .= "class NewClass() extends AbstractController {\n";    
$files = scandir($targetDir);
foreach ($files as $file) {
    echo "Reading File: " . $targetDir . $file . "\n";
    if (is_file($targetDir . $file)) {
        $content = file_get_contents($targetDir . $file);
        $method = rtrim($file, '.php');
        $output .= "#[Route('/{$method}', name: 'newclass_{$method}', methods: ['GET', 'POST'])]\n";
        $output .= "public function {$method}(Request \$request, Connection \$connection): Response\n";
        $output .= "{\n";
        $output .= str_replace("?>", "", str_replace("<?php", "", $content));    
        $output .= "}\n\n";
    }
}
$output .= "}";
file_put_contents('NewClass.php', $output);
