$url   =   'http://www.ltjxw.com/sca_tlist.asp?scasort=2 ';  
$file   =   file($url);  
$html   = " ";
foreach($file   as   $item   ){
$html.=$item;
}
$begin   =   "分类列表 ";$end   =   "7910条信息 ";

$str   =   '/([^分类列表]*) '.$begin. '([^7910条信息]*) '.$end. '/is ';

$re   =   preg_match   (
$str,
$html,
        $out);
print_r(   $out   );
echo   $re;
#(1)我想先截取网页中从“分类列表”   到   “7910条信息”之间的内容
#(2)然后再从结果中截取相关信息   该怎么做   是不是有什么\0   \1之类的
