可以'；t在同一类php中的另一个diff函数中获取一个函数中variable的集值 - Can't get the set value of varible in one function in other diff func in the same class php

Can't get the set value of varible in one function in other diff func in the same class php

我对这个变量"admin_user_id"有问题。。我想在一个函数中设置var的值，并在其他函数中使用该var值。。但问题是它给出了null。我认为这是该类的差异引用的bcz。。

class ChangeRequestProcessController extends AppController{
static $admin_user_id;
public function ajax_list_of_change_request(){
    $this->autoRender = false;
    $params = array();
    $params[] = $this->Auth->user('id');
    //debug($params);
    $result =  $this->AppProcess->callProcedure('ListOfChangeRequestProcess', $params);
    //echo("here:"+$result);
    $admin_user_id=$params[0];
    //debug( $this->admin_user_id);
    echo json_encode($result);
}
 public function application_attachment_upload_with_title() {
    $this->autoRender = FALSE;
    $attachment_array[]=$this->admin_user_id;///p_admin_user_id
    //$attachment_array[]="name";///p_uploaded_by
    $attachment_array[]=$_POST['title'];///p_attachment_title
   // $attachment_array[] = $loged_on_id;
    //$attachment_array[] = $_FILES[0]['name'];
    //$attachment_array[] = $_POST['title'];
    debug($attachment_array);
    $result = $application->AttachmentTemp->callProcedure('ChangeRequestAttachmentFinalAddWithTitle', $attachment_array);///call procedure
    echo json_encode($result);///result
}

如何在php中解决这个问题，使值保持不变（我认为静态var会解决这个问题……但它也会在函数内部给出未定义的var错误）？？？提前感谢

（这不适合评论框，所以我开始…）

假设

// your code to get this...
$admin_user_id = $params[0];

您可以使用以下方法将其存储在会话中：

if(!session_id()){
    session_start();
}
$_SESSION['admin_user_id'] = $admin_user_id; // again, assuming this is the value!

要读取它（在您的第二个调用/方法中），只需执行：

if(!session_id()){
    session_start();
}
$admin_user_id = $_SESSION['admin_user_id'];
