php 爬虫爬第一级：

 

$v)
{
	foreach($v as $vkey=>$k)
	{
		$id = iconv("utf-8","gb2312//IGNORE",$k["re_code"]);
		$re_name = iconv("utf-8","gb2312//IGNORE",$k["re_name"]);
		$re_parent = iconv("utf-8","gb2312//IGNORE",$k["re_parent"]);
		//echo iconv("UTF-8","GB2312",$k["re_code"]." ".$k["re_name"]." ".$k["re_parent"]);
		$sql="INSERT INTO t_zd_region (id, re_name, re_parent) VALUES
('$id','$re_name','$re_parent')";
if (!mysql_query($sql,$con))
  {
  die('Error: ' . mysql_error());
  }
echo "1 record added";
		//echo iconv("UTF-8","GB2312",$k["re_code"]." ".$k["re_name"]." ".$k["re_parent"]);
		echo "
";
	}
}

mysql_close($con);
//var_dump($citys);
?>

爬虫爬二三四级：

					foreach($v as $vkey=>$k)
						{

					('$id','$re_name','$re_parent')";
						if (!mysql_query($sql,$con))
						 {

					 die('Error: ' . mysql_error());
					 continue;
							 }
						echo "1 record added";
						echo $id;
						echo $re_name;
						echo $re_parent;
						echo "
";
						}
					}
				echo "
";
			}

爬虫爬最后一级：
