在a2hosting中，当我运行artisan migration时，我收到了以下错误消息：
Notice: Trying to get property of non-object in /home/letsmaka/letsmakan/laravel/database/query.php on line 677
迁移无法运行，因为它尝试执行已经运行的迁移。此错误还会影响使用雄辩关系方法的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') );
}
}
以下是我当地笔记本电脑的结果：

以下是lists
query.php方法的摘要
/**
* 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行是这段代码：
return $row->$column;
刚刚开始的错误发生在过去几周。在此之前，所有迁移都成功运行而没有错误。
为什么list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正常工作？
感谢。
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
)
为什么php行为变得不同以及如何让它像其他标准的php一样？
答案 0 :(得分：0)
通过将fetch设置添加到数据库设置，现在laravel数据库类的行为在整个平台上是相同的：
/*
|--------------------------------------------------------------------------
| 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,
