Laravel:我想返回块函数的结果，用Ajax在视图中得到它 - Laravel : I want to return the result of chunk function , to get it in the view with Ajax

Laravel : I want to return the result of chunk function , to get it in the view with Ajax

我想返回chunk的结果。问题是，当我使用foreach进行迭代时，我输入echo result它会显示结果但当我想返回结果时，会出现空白页

$tab = array();
Product::blabla ->chunk (500, function($results))
{

  foreach($results as $result)
  {
    array_push ($tab,$result);
    echo $results;// works
    return $results;// doesn't return anything
   }
}
return $tab; // to be sent to Ajax type get

闭包可以存储到变量中，所以只需添加到变量中。

$tab = Product::blabla()->chunk (500, function($results))
{
    // your logic
    return $results;
};
return $tab

这实际上不起作用，它只是返回true。您必须使闭包函数使用外部变量作为引用示例:

$output = [];
$tab = Product::blabla()->chunk (500, function($results) use (&$output))
{
    $output = array_combine($output, $results);
};
return $output;
