需求：採集攜程網酒店資訊

步驟：

1.     使用火車頭編寫採集規則並儲存到txt檔案
2.  編寫php指令碼讀取txt檔案並按照規則儲存到csv

程式碼：

<?php
/**
 * 讀取txt檔案，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';

/**
 * 字串過濾
 * @param  [type] $str [description]
 * @return [type]      [description]
 */
function filter_my($str){
	//這裡寫你自己的邏輯
	$str =  str_replace(' ', '', $str);
	$str =  str_replace('!!', '', $str);
	$str =  str_replace('[]', '', $str);
	$str =  str_replace('  ', '', $str);
	$tmp_arr = explode(',,', $str);
	return  $tmp_arr;
}

/**
 * 寫入csv
 * @param  [type] $dataList [description]
 * @return [type]           [description]
 */
function put_csv_my($dataList){
	//這裡寫你自己的邏輯
  $fp = fopen('hotel_2018-3-8.csv', 'w');  
  fputcsv($fp,array(iconv("UTF-8", "GB2312//IGNORE",'酒店名稱'),iconv("UTF-8", "GB2312//IGNORE",'地址'),
  	iconv("UTF-8", "GB2312//IGNORE",'房間數'),iconv("UTF-8", "GB2312//IGNORE",'開業時間'),iconv("UTF-8", "GB2312//IGNORE",'聯絡電話')));  
  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,$tel));   //fputcsv可以用陣列迴圈的方式進行實現  
	}
  fclose($fp);
