PHP根据元器件型号抓取500条数据并存入txt

有一个哥们找我抓取一下数据，根据500多个元器件型号，在某个网站去查并且写入txt文件。于是怎么简单怎么来，使用一个叫simple_html_dom.php的解析库。下载地址：https://github.com/zhiquan181/zqtoys/tree/master/YQJDatas

			fclose($open);

	    }
	    else{

        	fwrite($open,$arr_url[$i].";"."NO DATA!"."\r\n");
        	// var_dump($arr_url[$i].";"."NO DATA!");

	    }
	    $k++;
	}

	print_r('总共'.$k.'个数据已经检索完成！其中，查询有结果的有'.$j.'个，查询无结果的有'.$l.'个。');

运行如下：

生成txt

手动复制到excel，利用分隔符分列就可以了
