Delete directory with files in it?

Question

I wonder, what's the easiest way to delete a directory with all its files in it?

I'm using rmdir(PATH . '/' . $value); to delete a folder, however, if there are files inside of it, I simply can't delete it.

Answer 1

There are at least two options available nowadays.

1. Before deleting the folder, delete all its files and folders (and this means recursion!). Here is an example:

   function deleteDir(string $dirPath): void {
       if (! is_dir($dirPath)) {
           throw new InvalidArgumentException("$dirPath must be a directory");
       }
       if (substr($dirPath, strlen($dirPath) - 1, 1) != '/') {
           $dirPath .= '/';
       }
       $files = glob($dirPath . '*', GLOB_MARK);
       foreach ($files as $file) {
           if (is_dir($file)) {
               deleteDir($file);
           } else {
               unlink($file);
           }
       }
       rmdir($dirPath);
   }
   

2. And if you are using 5.2+ you can use a RecursiveIterator to do it without implementing the recursion yourself:

   function removeDir(string $dir): void {
       $it = new RecursiveDirectoryIterator($dir, RecursiveDirectoryIterator::SKIP_DOTS);
       $files = new RecursiveIteratorIterator($it,
                    RecursiveIteratorIterator::CHILD_FIRST);
       foreach($files as $file) {
           if ($file->isDir()){
               rmdir($file->getPathname());
           } else {
               unlink($file->getPathname());
           }
       }
       rmdir($dir);
   }
