类stdClass的对象无法转换为字符串-Laravel [英] Object of class stdClass could not be converted to string - laravel

问题描述

我正在关注此文档

在我的laravel 4项目中实现导出到Excel.

to implement export to Excel in my laravel 4 project.

因此，我试图从数组中生成excel文件，如下所示:

So am trying to generate excel file from array like this:

//$results is taken with db query

$data = array();
foreach ($results as $result) {
   $result->filed1 = 'some modification';
   $result->filed2 = 'some modification2';
   $data[] = $result;
}
Excel::create('Filename', function($excel) use($data) {

$excel->sheet('Sheetname', function($sheet) use($data) {

    $sheet->fromArray($data);

      });

})->export('xls');

但这会引发异常:

  Object of class stdClass could not be converted to string

我在做什么错了?

更新:

尝试过:

$data = get_object_vars($data);

结果为:

get_object_vars() expects parameter 1 to be object, array given

此:

$data = (array)$data;

导致初始错误.

推荐答案

$data确实是一个数组，但是它由对象组成.

$data is indeed an array, but it's made up of objects.

在创建内容之前将其内容转换为数组:

Convert its content to array before creating it:

$data = array();
foreach ($results as $result) {
   $result->filed1 = 'some modification';
   $result->filed2 = 'some modification2';
   $data[] = (array)$result;  
   #or first convert it and then change its properties using 
   #an array syntax, it's up to you
}
Excel::create(....
