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',

如何获取持续时间,文件等..值?
答案 0 :(得分:2)
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。
