php基于Snoopy解析网页html的方法

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：

set_time_limit(0);$user = array("20517", "20518");header("content-Type: text/html; charset=utf-8");require_once "./Snoopy.php";$snoopy = new Snoopy();//$uri = "http://www.juzimi.com/meitumeiju";$uri = "http://www.juzimi.com/meitumeiju?page=1";$snoopy->fetch($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);}
