本文实例讲述了PHP基于Snoopy解析网页html的方法。分享给大家供大家参考。具体实现方法如下：
fetch($uri);
$con = $snoopy->getResults();
$doc = new DOMDocument();
$doc->loadHTML($con);
/* make a result array ... */
$result = [];
/* go through all nodes which have class="baby" ... */
$i = 0;
foreach( ( new DOMXPath( $doc ) )->query( '//*[@id="bdshare"]' ) as $element ) {
$row = $doc->saveHTML($element);
$start = stripos($row,'{');
$end = stripos($row,'}');
$len = $end - $start + 1;
$json = substr($row,$start,$len);
$json = str_replace("'",'"',$json);
$obj = json_decode($json);
$pic = $obj->pic;
$desc = $obj->desc;
$filename = '/Uploads/meiju/card' . date('ymdhis') . $i . '.png';
$file = '/alidata/www/test' . $filename;
$image = file_get_contents($pic);
file_put_contents($file,$image);
}
希望本文所述对大家的PHP程序设计有所帮助。
