Php 如何使用codeigniter将变量从函数发送到同一控制器中的另一个函数

我在将变量数据从函数发送到同一控制器orderProcess中的另一个函数时遇到问题：

function endOrder(){
    $datap['invoice_pad'] = $invoice;
    $datap['date_end'] = date('d-m-Y');
    $datap['total_order'] = $grt;
    //$datap i want send to the function controller order()
}

function order(){
    //here should be $datap accepted
}

这是我的控制器订单流程：

function endOrder(){
    $datap['invoice_pad'] = $invoice;
    $datap['date_end'] = date('d-m-Y');
    $datap['total_order'] = $grt;
    //$datap i want send to the function controller order()
}

function order(){
    //here should be $datap accepted
}

函数endOrder（） {

}

函数顺序（$data）{

---

}

通常我会声明一个变量，并使用它传递所需的任何数据。但上面的答案也能实现你想要的

function __construct()
{
    $this->_datap = [];
}

function endOrder()
{
    $this->_datap['invoice_pad'] = $invoice;
    $this->_datap['date_end']    = date('d-m-Y');
    $this->_datap['total_order'] = $grt;
}

function order(){
    print_r(this->_datap);
}

虽然此代码可能会回答该问题，但提供有关此代码为什么和/或如何回答该问题的附加上下文可提高其长期价值。

function endOrder(){
    $datap['invoice_pad'] = $invoice;
    $datap['date_end'] = date('d-m-Y');
    $datap['total_order'] = $grt;
    return $datap;
}

function order(){
    $datap = $this->endOrder();
}

function __construct()
{
    $this->_datap = [];
}

function endOrder()
{
    $this->_datap['invoice_pad'] = $invoice;
    $this->_datap['date_end']    = date('d-m-Y');
    $this->_datap['total_order'] = $grt;
}

function order(){
    print_r(this->_datap);
}
