Question

我遇到了一个问题，我试图从外部URL中提取基本元数据，我已经成功地在大多数情况下这样做了，但它在字母上引起了一些字符问题Ääö当我打电话给mäenjaksa7-300x200.jpg的图片网址时出现像mÃ¤enjaksa7-300x200.jpg，我的代码在下面，感谢您的帮助。

function file_get_contents_curl($url)
{
$ch = curl_init();

curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);

$data = curl_exec($ch);
curl_close($ch);

return $data; }

$html = file_get_contents_curl($params['url']);

//parsing begins here:
$doc = new DOMDocument();
@$doc->loadHTML($html);
$nodes = $doc->getElementsByTagName('title');

//get and display what you need:
$urltitle = $nodes->item(0)->nodeValue;

$metas = $doc->getElementsByTagName('meta');

for ($i = 0; $i < $metas->length; $i++)
{
$meta = $metas->item($i);
if($meta->getAttribute('name') == 'description')
    $description = $meta->getAttribute('content');
if($meta->getAttribute('name') == 'keywords')
    $keywords = $meta->getAttribute('content');
if($meta->getAttribute('property') == 'og:image')
    $ogimage = $meta->getAttribute('content');
if($meta->getAttribute('rel') == 'image_src')
    $relimage = $meta->getAttribute('content');
}

 if( empty($ogimage) ) {
$metaimage = $relimage;
} else {
$metaimage = $ogimage;
}

解决方案：在下面添加发现：

 //Change encoding to UTF-8 from ISO-8859-1
    $html = iconv('UTF-8', 'ISO-8859-1//TRANSLIT', $html);

添加它：

<RelativeLayout
        ...
        android:background="@drawable/rowbgselector">

用php，奇怪的字符从url中拉出metadate？
