Question

我有一个未定义变量的问题。在view/somefolder/somefile.php中，他们回应了一些变异（<?php echo $news;?>）。我尝试了一切来找到这个变量的定义位置（在PHPStorm中的路径中查找），但没有结果。当我对print_r($GLOBALS)进行测试时，我得到了

[_ci_cached_vars:protected] => Array
                    (
                        [unread] => 0

在Codeigniter中，

从控制器加载视图。例如：

控制器：

// this file resides in application\controllers\mycontroller.php

class Mycontroller extends CI_Controller{
    function mypage() {
        $data = array('news' => 'some news');
        $this->load->view('page', $data);// will load views\page.php and pass the $data array
    }
}

查看

<!--this file resides in application\views\page.php -->
<html>
    <head></head>
    <body><?= $news; ?></body> 
</html>

要做到这一点，您的网址会说http://localhost/index.php/mycontroller/mypage（如果您在本地工作）

您的变量正在加载该视图的控制器中设置。

CodeIgniter，变量声明
