在foreach循环中实例化静态对象

标签： php mysql

嗨，所有人都迟到了，我认为疲倦会增加这一点，但我不能让这个PHP工作

我有一个用户类，并且在一个函数中通过id查找用户，然后将该人创建为对象。我正在尝试在foreach循环中创建此对象，以便从一系列ID中获取所有用户，以便我可以提取每个用户的电子邮件

foreach ($_GET['CaseStaffs'] as $admin ) {
    $user = Users::find_by_ips_id( $admin['EmployeeId'] );
    $return['staffEmail'][] = $user->email;
}
echo json_encode($return);

$_GET['CaseStaffs']是我从api电话中获得的json工作人员ID数组

每个循环它接缝给我创建对象但是如果我尝试从对象访问任何值我得到

  

尝试获取非对象的属性

这是$return['staffEmail'][] = $user->email;

行

$admin['EmployeeId']

似乎从函数api调用返回的是json字符串，而不是php数组或对象。使用json_decode（）将其转换为Object。

没有任何名为＆＃39; EmployeeId＆＃39;在这个json。它是响应字符串中的ID列表。

{"readyState":4,"responseText":"string(2) \"32\"\nstring(1) \"9\"\nstring(2) \"67\"\nstring(3) \"180\"\n","status":200,"statusText":"OK"}

你必须

$jsonarray = json_decode($_GET['CaseStaffs'],true);
$listofIDs = $jsonarray['responseText']; // to get the list of IDs, as string

但字符串看起来像是：

string（2）＆＃34; 32＆＃34; 字符串（1）＆＃34; 9＆＃34; 字符串（2）＆＃34; 67＆＃34; string（3）＆＃34; 180＆＃34;

所以你必须弄清楚如何从字符串中提取ID

$admin['EmployeeId']看起来很可疑，因为$admin是$_GET['CaseStaffs']中的每个值。

看到这样的网址已经非常罕见了：

http://example.com/file.php?CaseStaffs[]=1&CaseStaffs[]=2&CaseStaffs[]=3

要看到这个更多（我不知道这种语法是否有效）：

http://example.com/file.php?CaseStaffs[]['EmployeeId']=1&CaseStaffs[]['EmployeeId']=2&CaseStaffs[]['EmployeeId']=3

使用GET请求中的第一个URL，然后在您的代码中使用以下行：

$user = Users::find_by_ips_id( $admin );

另外，作为旁注，您应该一次检索所有用户，或者至少批量检索所有用户。一个接一个地做这件事很容易成为瓶颈。
