Answer 1

这样做..

<?php
$html='<html>
<head></head>
<body>
bla bla bla <br />
<a id="downloadbutton" href ="http://tomtuoi.com/file.exe";
</body>
</html>';
$dom = new DOMDocument;
@$dom->loadHTML($html);
foreach ($dom->getElementsByTagName('a') as $tag) {
    echo $tag->getAttribute('href'); //"prints" http://tomtuoi.com/file.exe
}

从html字符串中获取id的href值
