抓取全国行政区划（PHP）代码

Posted 2022-07-28 bywayboy

项目需要，简单写了一个抓取全国行政区划的代码。

 

class AreaCodeCtrl extends Controller

static function getSubstr($str, $leftStr, $rightStr)
   
	   $llen = strlen($leftStr);
	   $left = strpos($str, $leftStr);
	   $right = strpos($str, $rightStr,$left + $llen);

	   if($left <0 || $right < $left)
		   return "";

	   return substr($str, $left+$llen, $right - $left-$llen);
	
   public function area()
   
	   $prv = [
			['name'=>'湖北省','code'=>'42','cat'=>'000'], // 有字符集问题.
		];
	// http://www.stats.gov.cn/tjsj/tjbz/tjyqhdmhcxhfdm/2018/
	
	foreach($prv as $item) 
		$data = new Area([
			'code'=>$item['code'].'0000000000',
			'name'=>$item['name'],
		]);
		$data->save();
		Self::GetCode("http://www.stats.gov.cn/tjsj/tjbz/tjyqhdmhcxhfdm/2018/$item['code'].html");
	
		//Self::GetCode("http://www.stats.gov.cn/tjsj/tjbz/tjyqhdmhcxhfdm/2018/43.html");
   
   
	private static function GetCode($url)
		$raw = http_read($url);
		
		try 
			$raw = iconv('gbk','utf-8//IGNORE',$raw);
		catch(ErrorException $e)
			echo "iconv error \\n";
		
		
		$html = Self::getSubstr($raw,'名称</td>','</TD>');
		$dec = Self::getSubstr($html,"<tr class='","'>");
		$body = Self::getSubstr($html,"<tr class='$dec'><td>","</table>");
		$body = substr($body, 0, -12);
		$rows = explode("</td></tr><tr class='$dec'><td>",$body);
		foreach($rows as $row)
			if($row0 == '<')
				$suburl = substr($url, 0, strrpos($url,"/")+1).Self::getSubstr($row, "<a href='","'>");
				$cols = explode('</td><td>',$row);
				try 
					$data = new Area([
						'code'=>Self::getSubstr($cols[0],'>','<'),
						'name'=>Self::getSubstr($cols[1],'>','<')
					]);
					$data->save();
					echo("$data->code, $data->name\\n");
				catch(PDOException $e)
					Log::info("ERROR: $cols[0], $cols[1]");
				
				
				Self::getCode($suburl);
			else
				$cols = explode('</td><td>',$row);
				try
					if(count($cols)>2) 
						$data = new Area([
							'code'=>$cols[0],
							'name'=>$cols[2],
							'tcode'=>$cols[1],
						]);
					else
						$data = new Area([
							'code'=>$cols[0],
							'name'=>$cols[1],
						]);
					
					echo("$data->code, $data->name\\n");
					$data->save();
				catch(PDOException $e)
					Log::info("ERROR: $data->code, $data->name\\n");
