PHP 正在尝试获取 属性 'full_name' 的非对象

PHP Trying to get property 'full_name' of non-object

foreach ($data as $dt_row) {
    if ($coordinator != $dt_row->coordinator->full_name) {
        $sheet->setCellValue('A' . $row, "Zmiana " . $dt_row->shift_code . " - " . $dt_row->coordinator->full_name);
        $sheet->setCellValue('B' . $row, $dt_row->coordinator->position);
        $sheet->getStyle('A' . $row . ':B' . $row)->getFont()->setBold(true);
        $coordinator = $dt_row->coordinator->full_name;
        $row++;
    }
    $sheet->setCellValue("A" . $row, $dt_row->user->full_name);
    $sheet->setCellValue("B" . $row, $dt_row->user->position);
    $row++;
}

returns “正在尝试获取 属性 'full_name' 的非对象” 数据结构如下所示

 {
        "shift_code": "B",
        "coordinator": {
            "full_name": "name surname",
            "position": "Koordynator dzia\u0142u Kompletowania\/Monta\u017cu", ///language code here
            "shift_code": "B"
        },
        "user": {
            "full_name": "surname_emp name_emp",
            "position": "Starszy pracownik dzia\u0142u Kompletowania\/Monta\u017cu"
        }
    }

我想我尝试获取 属性 是正确的,但是 mb 我看不到某些东西

已修复必须添加 ->data foreach ($data->data as $dt_row) 感谢您的帮助
