$financeKxs = db('finance_kx')->select();
$hzs = db('cooperate')->select();
foreach ($financeKxs as $key => $value) {
foreach ($hzs as $k => $v) {
if($value['hzs']==$v['id']){
$value['hzs'] = $v['name'];
}
}
}
dump($financeKxs);

$financeKxs['hzs']没有改到，在foreach里面dump是修改了的，请大神帮我看下是哪里不对，同样的代码在5.0版本是可以，现在用的5.1就不行了。
