根据项目实践总结的一个类文件, mac/win下没乱码

简体中文 默认从gb2312转到utf-8

用法:

 // 导入:
 $arr = CSV::import($filepath);

 // 导出:
 $data = ['filename' => 'xxx', 'list' => [[xx,xx,x], [xx,xx,x]]];
 CSV::export($data);

 <?php

 class CSV
 {
     public static $csvError = '';

     public static function _SetError($error)
     {
         self::$csvError = $error;
     }

     /**
      * 读取csv文件成数组
      * @param string $filePath 文件路径
      * @return array|bool
      */
     public static function import($filePath)
     {
         setlocale(LC_ALL, 'zh_CN');

         if(!file_exists($filePath) || !is_readable($filePath)) {
             self::_SetError('文件不存在或者不可读');
             return FALSE;
         }

         $rows = array();
         $fp = fopen($filePath, 'rb');
         while (!feof($fp)) {

             $row = str_replace(array("\r\n", "\r", "\n"), '', fgets($fp));
             $rows[] = explode(',', iconv('GB2312', 'UTF-8', $row)); //简体中文编码转为 utf-8, gbk 兼容gb2312

         }
         return $rows;
     }

     /**
