未定义数组索引: index
不知道哪里有问题，希望各位大大帮忙看下
<?php
namespace app\admin\controller;
use think\Controller;
use think\Db;
class User extends Controller {
public function index(){
echo '123';
// $list = Db::query("SELECT * FROM `cms_user`");
echo '<pre>';
print_r($list);
}
}这样写可以正常显示<?php
namespace app\admin\controller;
use think\Controller;
use think\Db;
class User extends Controller {
public function index(){
echo '123';
$list = Db::name('user')->select();
echo '<pre>';
print_r($list);
}
}这样写就直接报下面的错[8] ErrorException in Mysql.php line 101
未定义数组索引: index
$info = [];
if ($result) {
foreach ($result as $key => $val) {
$val = array_change_key_case($val);
$info[$val['field']] = [
'name' => $val['field'],
'type' => $val['type'],
'notnull' => (bool) ('' === $val['null']), // not null is empty, null is yes
'index' => $val['index'],
'primary' => (strtolower($val['key']) == 'pri'),
'autoinc' => (strtolower($val['extra']) == 'auto_increment'),
];
}
}
return $this->fieldCase($info);
} 最佳答案
