成员函数和非对象

I have created a simple function for fetching xml:

我为获取xml创建了一个简单的函数:

function meteor(){
    $request_url = "http://site.com/xml.xml";
    $xml = simplexml_load_file($request_url) or die("feed not loading");
    return $xml;
 }

But I cant call to this function:

但我不能调用这个函数:

$xmls = new meteor();
echo $xmls->Kemo->Area;

I have not any output because meteor in not a class. In this situation, how can fetch data from function? Thanks in advance

因为流星不在一个级别，所以我没有任何输出。在这种情况下，如何从函数中获取数据?谢谢提前

4 个解决方案

#1

$xmls = meteor();
$xmls->Kemo->Area;

You can use new only with classes, to create a new object from that class. meteor is a function, not a class. What you want is to call the function instead, simply like this:

只能对类使用new，以从该类创建新对象。流星是一个函数，不是一个类。你想要的是调用函数，就像这样:

$xmls = meteor();

#3

meteor is a function not a class. i don't think you can create a

流星是一个函数而不是一个类。我认为你不能创造一个

new meteor();

#4

The basic code is wrong. Always remember that you cannot use the "new" keyword for instantiating functions. This "new" keyword will only work for instantiating classes into objects.

基本代码是错误的。记住，不能使用“new”关键字来实例化函数。这个“新”关键字只会用于将类实例化为对象。

Try calling the function directly into your code, for fetching the appropriate value. But before that I think you will need to modify your "meteor()" function according to what you want to achieve.

尝试将函数直接调用到代码中，以获取适当的值。但在此之前，我认为您需要根据您想要实现的目标修改您的“流星()”功能。

Hope it helps.
