如何获取所有生成网页的php文件的文件名？

   $files = scandir($directory);

   foreach ($files as $file) {

       if (pathinfo($file, PATHINFO_EXTENSION) === 'php') {

           $phpFiles[] = $file;

       }

   }

   if (is_dir($directory)) {

       $files = scandir($directory);

       foreach ($files as $file) {

           if ($file === '.' || $file === '..') {

               continue;

           }

           $path = $directory . '/' . $file;

           if (is_dir($path)) {

               $phpFiles = array_merge($phpFiles, getPhpFiles($path));

           } elseif (pathinfo($file, PATHINFO_EXTENSION) === 'php') {

               $phpFiles[] = $file;

           }

       }

   }

   return $phpFiles;
