php文章内容抓取

[yanfangphp]

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）

[liu510817387]

抓取 研究研究 phpquery

[xuzuning]

$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>

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。

[xuyanlu]

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

[果酱很好吃]

$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][]=$v1;
			}
		}
	}
}
echo "<pre>";
print_r($jifen);
print_r($sheshou);
echo "</pre>";

我输出出来的怎么是一个空数组

[傲雪星枫]

sohu的页面是gb2312的，采集后需要转utf8，否则会乱码

echo '<meta http-equiv="content-type" content="text/html;charset=utf-8">';

$url = 'http://sports.sohu.com/zhongchao.shtml';
$s = file_get_contents($url);
$s = iconv('GBK','UTF8', $s); // gb2312转utf8
preg_match_all('/(?<=<div class="turn cons">)\s<table.+table>/isU', $s, $m);

// 获取积分榜
preg_match_all('/<tr>\s*<td>(.+?)<\/td>\s*<td>(.+?)<\/td>\s*<td>(\d+)<\/td>\s*<td>(.+?)<\/td>\s*<\/tr>/i',$m[0][2],$scores);

$scoreboard = array();
for($i=0,$len=count($scores[1]); $i<$len; $i++){
	$tmp = array($scores[1][$i],strip_tags($scores[2][$i]),$scores[3][$i],$scores[4][$i]);
	array_push($scoreboard, $tmp);
}

print_r($scoreboard);

// 射手榜
preg_match_all('/<tr>\s*<td>(.+?)<\/td>\s*<td>(.+?)<\/td>\s*<td>(\d+)<\/td>\s*<td>(.+?)<\/td>\s*<\/tr>/i',$m[0][3],$shooters);

	$tmp = array($shooters[1][$i],strip_tags($shooters[2][$i]),$shooters[3][$i],$shooters[4][$i]);
