php从爬虫爬取的txt文件按行读取并写入保存到excel，csv中

需求：采集携程网酒店信息

步骤：

1.     使用火车头编写采集规则并保存到txt文件
2.  编写php脚本读取txt文件并按照规则保存到csv

代码：

<?php
/**
 * 读取txt文件，存入csv表格中
 */


$file_name = 'hotel_2018-3-8.txt';
$file = fopen($file_name,"r");
$data = [];
while(! feof($file))
  {
  	$str =  fgets($file);
  	$arr_line = filter_my($str);
  	$data[] = $arr_line;
  }

fclose($file);
put_csv_my($data);

echo 'OK';

/**
 * 字符串过滤
 * @param  [type] $str [description]
 * @return [type]      [description]
 */
function filter_my($str){
	//这里写你自己的逻辑
	$str =  str_replace(' ', '', $str);
	$str =  str_replace('!!', '', $str);
	$str =  str_replace('[]', '', $str);
	$str =  str_replace('  ', '', $str);
	$tmp_arr = explode(',,', $str);
	return  $tmp_arr;
}

/**
 * 写入csv
 * @param  [type] $dataList [description]
 * @return [type]           [description]
 */
function put_csv_my($dataList){
	//这里写你自己的逻辑
  $fp = fopen('hotel_2018-3-8.csv', 'w');  
  fputcsv($fp,array(iconv("UTF-8", "GB2312//IGNORE",'酒店名称'),iconv("UTF-8", "GB2312//IGNORE",'地址'),
  	iconv("UTF-8", "GB2312//IGNORE",'房间数'),iconv("UTF-8", "GB2312//IGNORE",'开业时间'),iconv("UTF-8", "GB2312//IGNORE",'联系电话')));  
  foreach ($dataList as $data) {
	  $name = iconv("UTF-8", "GB2312//IGNORE",isset($data[0]) ? $data[0] : '');
	  $addr = iconv("UTF-8", "GB2312//IGNORE",isset($data[1]) ? $data[1] : '');
	  $house = iconv("UTF-8", "GB2312//IGNORE",isset($data[2]) ? $data[2] : '');
	  $open = iconv("UTF-8", "GB2312//IGNORE",isset($data[3]) ? $data[3] : '');
	  $tel = iconv("UTF-8", "GB2312//IGNORE",isset($data[4]) ? $data[4] : '');
	  fputcsv($fp,array($name,$addr,$house,$open,$tel));   //fputcsv可以用数组循环的方式进行实现  
	}
  fclose($fp);  
}
