我以前在我的普通mysql_*连接中有这个:

mysql_set_charset("utf8",$link);
mysql_query("SET NAMES 'UTF8'");

我是否需要它用于PDO？我应该在哪里买到它？

$connect = new PDO("mysql:host=$host;dbname=$db", $user, $pass, array(PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION));

只要我将Laravel应用程序从MySQL移动到pSQL.我一直收到这个错误.

Response内容必须是实现__toString()的字符串或对象,给出"boolean".

我有一个API,假设要退回我的促销活动

HTTP://本地主机:8888/API /推广/ 1

public function id($id){
    $promotion = Promotion::find($id);
    dd($promotion); //I got something here
    return $promotion;
}

它曾用于返回我的促销,现在它返回错误.

DD($推广);

I got
