我的网站似乎停止了，我试图获取数据库返回的行数，但它似乎不想玩球...其他人能看到这个问题吗？
This is my query:
$check_friend_request = DB::table("friend_requests")
->where("request_sent_by_id", Auth::user()->user_id && "request_sent_to_id", $curUserID[1]);
and this is how I'm "attempting" to count the number of rows
$cfr = count($check_friend_request);
每当我try echo $cfr时，它会返回1，但应该返回0，因为尚未发送好友请求.我很可能错过了一些非常明显的事情，但任何帮助都会很棒！非常感谢.
你有以下代码
$check_friend_request = DB::table("friend_requests")
->where("request_sent_by_id", Auth::user()->user_id && "request_sent_to_id", $curUserID[1]);
It should be
$check_friend_request = DB::table("friend_requests")
->where("request_sent_by_id", "=", Auth::user()->user_id) // "=" is optional
->where("request_sent_to_id", "=", $curUserID[1]) // "=" is optional
->get();
然后，你可以使用
if($check_friend_request){
//...
}
Also, count($check_friend_request) will work because it returns an array of objects. read more about Query Builder on Laravel Website.
