Question

我无法弄明白:(

完整的脚本......

故障线由“此线”标注我可以把它们拿出来，脚本可以工作但只有一半:(

Answer 1

$kernel->db->row是一个数组吗？我想这是一个对象，你不能添加对象和数组。

Answer 2

我们知道$kernel->vars['stats']是一个数组，因为：

$kernel->vars['stats'] = array();

接下来是您的问题：

$kernel->vars['stats']=$kernel->vars['stats'] + $kernel->db->row( ... );

+表示2个数组的并集，因此$kernel->db->row(...)必须是数组。

是吗？

Answer 3

您好像期待一个数组作为row方法的返回值。不知道你的DB类，我们不能说这是否属实，但无论如何，你应该首先检查返回类型。（也是出于错误的情况）

$row = $kernel->db->row( "SELECT `file_id` .... " );

if (is_array($row)) 
 $kernel->vars['stats'] = $kernel->vars['stats'] + $row;

致命错误：不支持的操作数类型
