php 信息采集程序代码

Jun 13, 2016 pm 12:24 PM
http php url code information address copy program collection front page

复制代码 代码如下:



//采集首页地址
$url="http://emotion.pclady.com.cn/skills/";
//获取页面代码
$rs=file_get_contents($url);
//设置匹配正则
//$fp=fopen("text.txt","a");
//$fw=fwrite($fp,$rs);
//fclose($fp);
/*href="http://emotion.pclady.com.cn/skills/0903/376476.html"
target=_blank>留住你身边的好男人
*/
$preg='/]+\">(.*)/i';
//进行正则搜索
preg_match_all($preg,$rs,$title);
//计算标题数量
$count=count($title[0]);
echo $count."
";
//通过标题数量进行内容采集
for ($i=0;$i
//设置内容页地址
$pr='/
]+\">/isU';
preg_match_all($pr,$title[0][$i],$jurl);
$substr=substr($jurl[0][0],9);
$curl=substr($substr,0,-18);
//获取内容页代码
$c=file_get_contents($curl);
//设置内容页匹配正则
$pc='/
]+\">/i';
//进行正则匹配搜索
preg_match($pc,$c,$content);
//输出标题
echo $title[0][$i]."
";
echo $title[1][$i]."
";
$concount=count($content[0]);
echo $concount."
";
echo $content[0][0];
for ($j=0;$j
}
}
?>


通过检测,$c已经是内容页的数据流了,可是$pc这个的正则表达式为什么只匹配
