Question

我正在研究CI并尝试使用Pthreads，我在控制器中有一个函数，它将调用线程，并且我已经使用new而不是$ this-＆gt; load-＆gt;来线程化了库的对象。库作为我的线程扩展Thread类，所以它不允许我做load-＆gt;库所以我使用new实例化了类这是我的控制器：

defined('BASEPATH') OR exit('No direct script access allowed');
include_once APPPATH.'/libraries/feedstart_class.php';
include_once APPPATH.'/libraries/test/thread.php';

    class Welcome extends CI_Controller {

        public function __construct() {
            parent::__construct();
            $this->load->library('event_library');
            $this->load->model('global_model');
        }
        public function testThreadCommandLine() {
            $mythreads = array();
            $ci_obj = & get_instance();
            for($i = 0;$i<5;$i++) {
                $mythreads[$i] =  new MyThread();
                $mythreads[$i]->setIndex($i);
                $mythreads[$i]->setCI($ci_obj);
                $mythreads[$i]->start();
            }`enter code here`
        }
    }

这是我的主题类

include_once APPPATH.'/libraries/common_event_library.php';
    Class MyThread extends Thread
    {
        private $_index;
        private $_CI;
        public function __construct() {

        }
        public function setIndex($index) {
            $this->_index = $index;
        }
        public function setCI($ci_obj) {
            $this->_CI = $ci_obj;
        }
        public function getIndex() {
            return $this->_index;
        }
        public function run() {
            sleep(rand(0,10));
            echo "The index of the object is ".$this->_index;
            $common_event_library =  new Common_event_library($this->_CI);
            $common_event_library->display();//gets all sports categories from our system
            echo "<br>";
        }
    }

这是我的库

Class Common_event_library {
    private $_CI;
    public function __construct($ci_instance) {
        $this->_CI = $ci_instance;
    }
    public function display() {
        $this->_CI->db->select("*");
        $this->_CI->db->from("sports_cateogry");
        $result = $this->_CI->db->get()->result();
        print_r($result);
    }
}

当我从浏览器和命令行运行testThreadCommandLine时，它会说：注意：尝试在C：\ xampp \ htdocs \ CI \ application \ libraries \ common_event_library.php中获取非对象的属性

Answer 1

Common_event_library的构造函数应该是

function __construct($ci_instance){
    $this->_CI = $ci_instance;
}

你在这里传递它，但没有任何东西接收它。：

$ common_event_library = new Common_event_library（$ this-＆gt; _CI）;

Answer 2

Common_event_library（）中的构造函数必须包含父:: __构建体（）;

无法在pthreads中执行CI get_instance（）
