php文章内容抓取

本帖最后由 yanfangphp 于 2014-08-13 10:14:37 编辑 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)



------解决方案--------------------
$url = 'http://sports.sohu.com/zhongchao.shtml';<br />$s = file_get_contents($url);<br />preg_match_all('/(?<=<div class="turn cons">)\s<table.+table>/isU', $s, $m);<br />print_r(preg_grep('/名次/', $m[0]));
Copy after login
Array<br />(<br />    [2] => <br /><table border=0 cellSpacing=0 cellPadding=0 width="100%"><br /><tbody><br /><tr><br /><th width="15%">名次</th><br /><th width="47%">球队</th><br /><th width="9%">场次</th><br /><th width="29%">积分</th></tr><br /><tr><br /><td>01</td><br /><td><a href="http://sports.sohu.com/s2010/7742/s277701524/" target="_blank">广州恒大</a></td><br /><td>20</td><br /><td>45</td><br /></tr><br /><tr><br /><td>02</td><br /><td><a href="http://sports.sohu.com/s2006/7742/s242155493/" target="_blank">北京国安</a></td><br />......
Copy after login
接下来自己做
------解决方案--------------------
给你推荐个类 simple_html_dom

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


结果

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