如上,怎么将$title 像$query一样,在函数内部使用?
$result = UserMenus::with(['menu'=>function($query){
$query->where('title',$title);
}])->where('user_id',$userId)->first();

<code>php</code><code>$result = UserMenus::with(['menu'=>function($query) use($title){
$query->where('title',$title);
}])->where('user_id',$userId)->first();
</code>

<code>$result = UserMenus::with(
[
    'menu'=>function($query){
                global $title;
                $query->where('title',$title);
            }
])->where('user_id',$userId)->first();
</code>

话说PHP 有全局函数,你加global 不行吗?
