抓取 研究研究 phpquery

$url = 'http://sports.sohu.com/zhongchao.shtml';$s = file_get_contents($url);preg_match_all('/(?<=)\s<table.+table>/isU', $s, $m);print_r(preg_grep('/名次/', $m[0]));

可以使用preg_match去抓取对应的HTML代码然后再正则过滤你想要的数据即可。

给你推荐个类 simple_html_dom

include "simple_html_dom.class.php";$url = "http://sports.sohu.com/zhongchao.shtml";$dom = new simple_html_dom();$html = $dom->load(file_get_contents($url));$res = $html->find("div#turnIDB div.turn");# 积分榜echo $res[0]->outertext;# 射手榜echo $res[1]->outertext;

$str=file_get_contents("http://sports.sohu.com/zhongchao.shtml");preg_match_all('/\s*(.+?)<\/td>\s*(.+?)<\/td>\s*(\d+)<\/td>\s*(.+?)<\/td>\s*<\/tr>/i',$str,$match1);foreach($match1 as $k=>$v){	if($k!=0){		foreach($v as $k1=>$v1){			if($k1<=15){				$jifen[$k][]=$v1;			}else{				$sheshou[$k][]=$v1;			}		}	}}echo "
";print_r($jifen);print_r($sheshou);echo "

sohu的页面是gb2312的，采集后需要转utf8，否则会乱码
