[英]Laravel fetch only one value from databse without stdClass Object
Hello people here is my code below... 大家好,这是我的以下代码...
$uid = DB::table('users')
->where('email', '=', Input::get('email'))
->select('email')
->get();
print_R ($uid);
this will output Array ( [0] => stdClass Object ( [email] => myemail@someemail.om ) )
I want only [email] => myemail@someemail.om
so that i can save in session, Without using foreach loop
can we get an outfput [0] => stdClass Object
???? 这将输出
Array ( [0] => stdClass Object ( [email] => myemail@someemail.om ) )
我只想要[email] => myemail@someemail.om
这样我就可以保存在会话中,而无需使用foreach loop
我们可以得到输出[0] => stdClass Object
吗?

这是您的示例的更新代码:
$uid = DB::table('users')
->where('email', '=', Input::get('email'))
->pluck('email');
As for laravel3 the docs state that upper example changes to : 至于laravel3,文档指出上面的示例变为:
$uid = DB::table('users')
->where('email', '=', Input::get('email'))
->only('email');
