解析错误，在包含SimplePie RSS Script时期望“T_FUNCTION”

问题描述：

I've narrowed down my issue to the line when I include the SimplePie RSS script (simplepie.inc). I'm not sure why exactly it's throwing this error, but I thought StackOverflow might have more insight than I have been able to find via Google thus far.

Here's the code to the simple class that I'm using to get the SimplePie feed results:

<?php

// Include SimplePie
require_once("simplepie.inc");

class Channel
{
    public $feed = new SimplePie();

    private $feedURI = "";

    function __construct($URI)
    {
        $this->feedURI = $URI;

        $this->feed->set_feed_url($this->feedURI);
        $this->feed->init();
        $this->feed->handle_content_type();
    }
}

?>

If you have any insight at all for me that would be awesome! Thank you!

当我包含SimplePie RSS脚本（simplepie.inc）时，我已将问题范围缩小到了界限。我不确定为什么它会引发这个错误，但我认为StackOverflow可能比我迄今为止通过Google找到的更多洞察力。 p>

这是简单类的代码我正在使用它来获取SimplePie提要结果： p>

 ＆lt;？php 
 
 //包含SimplePie 
require_once（“simplepie.inc”）; 
  
class Channel 
 {
 public $ feed = new SimplePie（）; 
 
 private $ feedURI =“”; 
 
 function __construct（$ URI）
 {
 $ this-＆gt; feedURI =  $ URI; 
 
 $ this-＆gt; feed-＆gt; set_feed_url（$ this-＆gt; feedURI）; 
 $ this-＆gt; feed-＆gt; init（）; 
 $ this-＆gt; feed-  ＆gt; handle_content_type（）; 
} 
} 
 
？＆gt;

 如果您对我有任何见解，那将是非常棒的！ 谢谢！ p>

答

You can't instantiate a class when defining a property. Only constant values are valid syntax. Instantiate $feed inside the constructor instead:

public $feed;

public function __construct($URI)
{
    $this->feed = new SimplePie();
    // ...
}

From the manual:

This declaration may include an initialization, but this initialization must be a constant value--that is, it must be able to be evaluated at compile time and must not depend on run-time information in order to be evaluated.

答

public $feed = new SimplePie();

You can't use a function or class assignment in the property declaration. Define as NULL, and set the property value as new SimplePi
