在foreach循环中,取消链接似乎不起作用

因此,我有以下代码,当我从数据库中删除一行时,我也会删除与之关联的文件,代码运行平稳,实际上我可以从数据库中删除行,但不知何故,我无法从服务器目录中删除文件,请注意,行“photo\u filename”包含一个名称,如“photo.png”等,也可以调用_ 目录 _从文件返回如下路径“ 。。。 \桌面\项目/过程”,我甚至没有收到任何警告,如果取消链接成功,我尝试回显一个字符串,如果没有成功,则回显另一个字符串,但奇怪的是,我没有得到任何输出,就好像循环没有运行一样,有人能告诉我这里缺少的东西的正确方向吗。谢谢

try {
  $db->beginTransaction();    // Begin transaction
  $query = "DELETE FROM properties "
    . " WHERE property_id = :property_id";  // Delete requested property.
  $stmt = $db->prepare($query);
  $stmt->bindParam(":property_id", $property["property_id"], PDO::PARAM_INT);
  $stmt->execute();
  $query = "SELECT * FROM photos "
    . " WHERE property_id = :property_id";
  $stmt = $db->prepare($query);
  $stmt->bindParam(":property_id", $property["property_id"], PDO::PARAM_INT);
  $stmt->execute();
  foreach ($stmt->fetchAll(PDO::FETCH_ASSOC) as $photo) {
    try {
      unlink(__DIR__ . "/../img/" . $photo["image_filename"])
    } catch (Exception $e) {
      throw $e;
    }
  }
  $query = "DELETE FROM photos "
    . " WHERE property_id = :property_id";
  $stmt = $db->prepare($query);
  $stmt->bindParam(":property_id", $property["property_id"], PDO::PARAM_INT);
  $stmt->execute();
  $db->commit();
} catch (Exception $e) {    // If there is a problem
  $db->rollBack();  //If there was a problem undo the whole attempt to insert
  $session->getFlashBag()->add("error", "Hubo un problema" . $e->getMessage()); // Display a message
  redirect("/show.php?id=".$property_id); // And redirect
  exit;
