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。
