"<br />";  }  else  {  $file1=$_FILES["file"]["name"];  $file1=explode('.',$file1);  $file1=time().'.'.$file1[1];   $content = '';  $length = 0;  $fp = fopen($_FILES["file"]["tmp_name"],'r');  if($fp)  {  $f = fstat($fp);  $length = $f['size'];  while(!feof($fp))  {  $content .= fgets($fp,8192);  }  }  $upload_file_options = array('content' => $content, 'length' => $length);  $upload_file_by_content=$oss_sdk_service->upload_file_by_content($bucket, $file1, $upload_file_options);  $data = $this -> Admin_model -> mGetCorpInfo();  $oldPath = $data['logo_file_path'];  if($oldPath!=''){  $delete_object = $oss_sdk_service->delete_object($bucket,$oldPath);  }   $this -> Admin_model -> mUpdateCorpPhoto($file1);  //header("Location:".$_SERVER["HTTP_REFERER"]);  echo '<script>alert("保存成功");</script>';  redirect('cSchool','refresh');  }  }
