我尝试获得一些attiributue值。但没有机会。下面你可以看到我的代码和解释。如何获取持续时间,文件等..值?

$url="http://www.some-url.ltd";

    $dom = new DOMDocument;
    @$dom->loadHTMLFile($url);
    $xpath = new DOMXPath($dom);
    $the_div = $xpath->query('//div[@id="the_id"]');
    foreach ($the_div as $rval) {
        $the_value = trim($rval->getAttribute('title'));
        echo $the_value;
    }

以下输出:

{title:'title',
                description:'description',
                scale:'fit',keywords:'',
                file:'http://xxx.ccc.net/ht/2012/05/10/419EE45F98CD63F88F52CE6260B9E85E_c.mp4',
                type:'flv',
                duration:'24',
                screenshot:'http://xxx.ccc.net/video/2012/05/10/419EE45F98CD63F88F52CE6260B9E85E.jpg?v=1336662169',
                suggestion_path:'/videoxml/player_xml/61319',
                showSuggestions:true,
                autoStart:true,
                width:412,
                height:340,
                autoscreenshot:true,
                showEmbedCode:true,
                category: 1,
                showLogo:true
                                                }

如何获取持续时间,文件等..值?

怎么样?
$parsed = json_decode($the_value, true);
$duration = $parsed['duration'];

编辑: 由于json_decode()需要正确的JSON格式(键名和值必须用双引号括起来),我们应该将原始格式修复为正确的格式。所以这是代码:

function my_json_decode($s, $associative = false) {
$s = str_replace(array('"', "'", 'http://'), array('\"', '"', 'http//'), $s);
        $s = preg_replace('/(\w+):/i', '"\1":', $s);
        $s = str_replace('http//', 'http://', $s);
        return json_decode($s, $associative);
}

$parsed = my_json_decode($var, true);

函数my_json_decode取自this answer,略有修改。
