推荐答案

您应该更新以下行 -

You should update below line -

取消链接（'upload_attachments /'.$ del_image-> attched_files）;

unlink('upload_attachments/'.$del_image->attched_files);

//使用此更新

unlink（'upload_attachments /'.$ del_image [0] ['attched_files']）;

unlink('upload_attachments/'.$del_image[0]['attched_files']);
