程式如下:

$total = db_num_rows($rs);
				//echo 'total:<br>'.$total.'<br>';
				//exit;
				if ($total > 0) {
					while ($row = db_fetch_object($rs)) {
						for ($i = 0; $i < $fields; $i++) {
							if (function_exists('mysqli_fetch_field_direct')) {
								$fieldinfo = mysqli_fetch_field_direct($rs, $i);
								$field_name = $fieldinfo->name;
								//echo '$row->$primary_key:'.$row->$primary_key.' => $fieldinfo->name:'.$fieldinfo->name.' => $row->$field_name:'.$row->$field_name.'<br>';
								//echo 'i:'.$i.' => '.$fieldinfo->name.' => '.$row->$field_name.'=>'.$row->$primary_key.'<br>';
								$result_value[$row->$primary_key][$fieldinfo->name] = $row->$field_name;
							} else {
								$fname = mysql_field_name($rs, $i);
								$result_value[$row->$primary_key][$fname] = $row->$fname;
							}
						}
					}
				}

錯誤在

$result_value[$row->$primary_key][$fieldinfo->name] = $row->$field_name;

錯誤訊息為
Warning: Undefined property: stdClass::$ AND name != '根目錄' in C:\web\budget2020\lib\common_wizard.php on line 989

更正：
抱歉，各位，我發現此非該程式有問題，而是引入變數錯誤導致的。已經找到問題了。
