php文章内容抓取

求大神帮忙抓取这个网页http://sports.sohu.com/zhongchao.shtml的排行榜部分的数据（包括积分榜和射手榜）

回复讨论(解决方案)

抓取 研究研究 phpquery

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

Array(    [2] => <table border=0 cellSpacing=0 cellPadding=0 width="100%"><tbody><tr><th width="15%">名次</th><th width="47%">球队</th><th width="9%">场次</th><th width="29%">积分</th></tr><tr><td>01</td><td><a href="http://sports.sohu.com/s2010/7742/s277701524/" target="_blank">广州恒大</a></td><td>20</td><td>45</td></tr><tr><td>02</td><td><a href="http://sports.sohu.com/s2006/7742/s242155493/" target="_blank">北京国安</a></td>......

接下来自己做

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;

结果

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

后面的自己处理吧

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

我输出出来的怎么是一个空数组

sohu的页面是gb2312的，采集后需要转utf8，否则会乱码
