PHP头像没有放在文件夹中？

Question

我的服务器去了/ var / www / html / uploads。我尝试在上传之前放一些，但它们似乎没有起作用。

if ($_FILES['photo']['name']) {
         $valid_file = true;
         if (!$_FILES['photo']['error']) {

              $new_file_name = strtolower($_FILES['photo']['name']);
              $pathImage = SITE_ROOT . '/uploads/' . $new_file_name;
              if ($_FILES['photo']['size'] > (1024000)) { // Maximum 1MB 
              image
                   $valid_file = false;
                   $message = 'Oops!  Your file\'s size is to large.';
              }

              if ($valid_file) {
                   move_uploaded_file($_FILES['photo']['tmp_name'], $pathImage);
