php - 调用数组 php 上的成员函数 where()

Question

        $customers = \dibi::select('*')->from('accounts')->fetchAll();
    if($username){
        $customers = $customers->where("username", $username);
    }

我有这个代码的问题。错误是：

调用数组上的成员函数 where()。

Answer 1

fetchAll返回ISelection。您不会在 ISelection 上调用 Where

if($username){
  $customers = \dibi::select('*')->from('accounts')->where("username", $username)->fetchAll();
}

或者

$customersTable = \dibi::select('*')->from('accounts');

if($username){
  $customersTable = \dibi::select('*')->from('accounts')->where("username", $username);
}

$customers = $customersTable->fetchAll();
