有谁知道如何访问已由另一个函数更新的公共控制器变量的值？

调节器
class MyController extends CI_Controller {
public $variable = array();
function __construct() {
parent::__construct();
}
function index(){
$this->variable['name'] = "Sam";
$this->variable['age'] = 19;
}
function another_function(){
print_r($this->variable);
}
}
当我调用another_function()时,我得到一个空数组..可能是什么问题？
任何帮助将是apreciated ..
你必须使用构造函数,而不是index().
原文链接：https://www.f2er.com/php/134900.htmlclass MyController extends CI_Controller {
public $variable = array();
function __construct() {
parent::__construct();
$this->variable['name'] = "Sam";
$this->variable['age'] = 19;
}
function index(){
}
function another_function(){
print_r($this->variable);
}
}
如果要调用index(),则调用another_function(),尝试使用CI session类.
class MyController extends CI_Controller {
public $variable = array();
function __construct() {
parent::__construct();
$this->load->library('session');
if ($this->session->userdata('variable')) {
$this->variable = $this->session->userdata('variable');
}
}
function index(){
$this->variable['name'] = "Sam";
$this->variable['age'] = 19;
$this->session->set_userdata('variable',$this->variable);
}
function another_function(){
print_r($this->variable);
}
}
