本文實例講述了php基于Snoopy解析網頁html的方法。分享給大家供大家參考。具體實現方法如下:
- 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);
- }
希望本文所述對大家的php程序設計有所幫助。
