Question

我想把xml（网站）加工成php数组。

我已经尝试了以下代码，该代码适用于结果中的每一个但我需要得到总页数，我无法看到我如何能够做到这一点。

function get_content($url) 
    /// basically opens the page and stores it as a variable. Buggered if I know how it works! 
    {   
        $ch = curl_init();  
        curl_setopt ($ch, CURLOPT_URL, $url);
        curl_setopt ($ch, CURLOPT_HEADER, 0);
        ob_start();
        curl_exec ($ch);
        curl_close ($ch);
        $string = ob_get_contents();
        ob_end_clean();
        return $string;
        $string = NULL;
        $ch = NULL;
        $url = NULL;
    }
$url = "url";
$content = get_content($url);
$content_x = explode("<result>", $content);

foreach ($content_x as $item)
    {
        $p1 = strpos($item, '<title>');
        $p2 = strpos($item, '</title>');
        $l1 = $p2 - $p1;
        echo '<br>'.$title = substr($item, $p1, $l1);
    }

xml网站Feed

<?xml version="1.0" encoding="UTF-8"?>
<response version="2">

    <totalpage>1005</totalpage>

    <results> 
        <result>
            <title>test</title>
            <title2>test2</title2>
            <title3>test3</title3>
        <result>
                <result>
            <title>test</title>
            <title2>test2</title2>
            <title3>test3</title3>
        <result>
                <result>
            <title>test</title>
            <title2>test2</title2>
            <title3>test3</title3>
        <result>
                ........so on

    <results>

</response>

我需要总页数并且每次都在结果中

如何获取总页数，这是处理结果的更好方法

你绝对不应该使用字符串操作来尝试解析XML。有许多PHP库可以做到这一点。我可能会推荐SimpleXML。

用法是：

$xml = simplexml_load_string($content);
$totalpage = $xml->response->totalpage;

php进程xml进入数组
