使用array_merge函数进行结果合并

就这么简单..却困扰了一天...神经了都！

$article1 = M('article')->field('*')->order('id desc')->limit(0,3)->select();
$article2 = M('article')->field('*')->order('id desc')->limit(3,3)->select();
$article3 = M('article')->field('*')->order('id desc')->limit(3,3)->select();
$lists[] = array_merge($article2,$article1,$article3);
dump($lists);
