使用Simplepie弃用错误 [英] Getting deprecated error with Simplepie

问题描述

我已经安装了最新的Simplepie代码(1.2.1)，并且正在使用它们提供的演示代码:

I have installed the latest Simplepie code (1.2.1) and I am using the demo code they provide:

<?php

require 'simplepie.inc';

$url = 'http://news.google.com/news?ned=us&topic=h&output=rss';

$feed = new SimplePie();
$feed->set_feed_url($url);
$feed->init();

// default starting item
$start = 0;

// default number of items to display. 0 = all
$length = 0; 

// if single item, set start to item number and length to 1
if(isset($_GET['item']))
{
    $start = $_GET['item'];
    $length = 1;
}

// set item link to script uri
$link = $_SERVER['REQUEST_URI'];

// loop through items
foreach($feed->get_items($start,$length) as $key=>$item)
{

    // set query string to item number
    $queryString = '?item=' . $key;

    // if we're displaying a single item, set item link to itself and set query string to nothing
    if(isset($_GET['item']))
    {
            $link = $item->get_link();
            $queryString = '';        
    }

    // display item title and date    
    echo '<a href="' . $link . $queryString . '">' . $item->get_title() . '</a>';
    echo ' <small>'.$item->get_date().'</small><br>';

    // if single item, display content
    if(isset($_GET['item']))
    {
            echo ' <small>'.$item->get_content().'</small><br>';
    }
    echo '<br>';
}

?>

但是，当我在浏览器中加载页面时，我会看到数十行内容:

However, when I load the page in my browser, I get dozens of lines saying:

Deprecated: Assigning the return value of new by reference is deprecated in /home/pliggs/public_html/rss/simplepie.inc on line 7722

有人知道怎么了吗?

我进行了他们的兼容性测试，结果表明所有事情都已通过.

I ran their compatibility test and it shows all things have passed.

推荐答案

您需要在代码中查找"=& new"的每个实例，然后删除&"现在已弃用.该代码中大约有116次出现.它与对象实例化的副本和引用有关.

You need to find every instance of "=& new" in the code and delete the "&" which is now deprecated. There are approximately 116 occurrences in the code. It has to do with copies and references of object instantiation.
