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);

}

希望本文所述对大家的php程序设计有所帮助。
