在 a2hosting 中,当我运行工匠迁移时,我收到以下错误消息:

Notice: Trying to get property of non-object in /home/letsmaka/letsmakan/laravel/database/query.php on line 677

并且迁移无法运行,因为它尝试执行已经运行的迁移。此错误也会影响使用 eloquent 关系方法的 Web 应用程序。

我创建了一个简单的任务来测试这个错误:

class Test_Query_Lists_Task {

  public function run($arguments)
  {
    print_r( DB::table('laravel_migrations')->where_bundle('application')->lists('name') );
  }

}

这是我本地笔记本电脑的结果:

$ php artisan test_query_lists

这是lists方法的片段query.php

/**
 * Get an array with the values of a given column.
 *
 * @param  string  $column
 * @param  string  $key
 * @return array
 */
public function lists($column, $key = null)
{
  $columns = (is_null($key)) ? array($column) : array($column, $key);

  $results = $this->get($columns);

  // First we will get the array of values for the requested column.
  // Of course, this array will simply have numeric keys. After we
  // have this array we will determine if we need to key the array
  // by another column from the result set.
  $values = array_map(function($row) use ($column)
  {
    return $row->$column;

  }, $results);

  // If a key was provided, we will extract an array of keys and
  // set the keys on the array of values using the array_combine
  // function provided by PHP, which should give us the proper
  // array form to return from the method.
  if ( ! is_null($key) && count($results))
  {
    return array_combine(array_map(function($row) use ($key)
    {
      return $row->$key;

    }, $results), $values);
  }

  return $values;
}

第 677 行是以下代码: return $row->$column;

刚刚开始的错误发生在最近几周。在此之前,所有迁移都成功运行,没有错误。

为什么列表方法使用的匿名函数无法运行?需要在 php 中启用哪些设置才能使其工作?

谢谢。

更新

我尝试通过添加以下内容来调试此问题:

675     $values = array_map(function($row) use ($column)
676     {
677       print_r($row);
678       return $row->$column;
679     
680     }, $results);

在我当地,我得到了这个:

stdClass Object
(
    [name] => 2012_12_30_170932_create_session_table
)

但是在 a2hosting 中,我得到了这个:

Array
(   
    [name] => 2012_12_30_170932_create_session_table
    [0] => 2012_12_30_170932_create_session_table
)

php 行为如何变得不同以及如何使它像其他标准 php 一样工作?

通过将 fetch 设置添加到数据库设置,现在 laravel 数据库类的行为跨平台相同:

/*
|--------------------------------------------------------------------------
| PDO Fetch Style
|--------------------------------------------------------------------------
|
| By default, database results will be returned as instances of the PHP
| stdClass object; however, you may wish to retrieve records as arrays
| instead of objects. Here you can control the PDO fetch style of the
| database queries run by your application.
|
*/

'fetch' => PDO::FETCH_CLASS,
