php读取csv时中文乱码的解决办法:首先在导入csv的php脚本文件头部加上相应代码;然后使用【$row】进行转义,将中文编码读取出来;最后使用一个【fgetcsv()】方法的替代函数,防止php该函数自带着一些bug即可。

php读取csv时中文乱码的解决办法:

1、首先讲linux,不管是centos或者Ubuntu。在导入csv的php脚本文件头部加上如下代码:

setlocale(LC_ALL,array('zh_CN.gbk','zh_CN.gb2312','zh_CN.gb18030'));
Copy after login

这段代码的作用是改变脚本默认编码,因为操作系统的编码格式不是GBK所以,读取中文的时候会乱码。

2、接着讲windows,我们在读取csv数据的时候,会有一个while循环遍历每一行的数据,而读取的每一行数据,就需要我们进行转义,将中文编码读取出来。代码如下:

$row = eval('return '.iconv('gbk','utf-8',var_export($row,true)).';');
Copy after login

$row,就是读取出来每一行的数据变量。

3、最后,贴一个fgetcsv()方法的替代函数,这种是针对有些老版本的php该函数自带着一些bug的情况。如果上边两点还是没办法解决您的问题,您可以尝试一下使用该函数,与前边两点配合使用。

function fgetcsv_reg(& $handle, $length = null, $d = ',', $e = '"') {
   $d = preg_quote($d);
   $e = preg_quote($e);
   $_line = "";
   $eof=false;
   while ($eof != true) {
       $_line .= (empty ($length) ? fgets($handle) : fgets($handle, $length));
       $itemcnt = preg_match_all('/' . $e . '/', $_line, $dummy);
       if ($itemcnt % 2 == 0)
           $eof = true;
   }
   $_csv_line = preg_replace('/(?: |[ ])?$/', $d, trim($_line));
   $_csv_pattern = '/(' . $e . '[^' . $e . ']*(?:' . $e . $e . '[^' . $e . ']*)*' . $e . '|[^' . $d . ']*)' . $d . '/';
   preg_match_all($_csv_pattern, $_csv_line, $_csv_matches);
   $_csv_data = $_csv_matches[1];
   for ($_csv_i = 0; $_csv_i < count($_csv_data); $_csv_i++) {
       $_csv_data[$_csv_i] = preg_replace(&#39;/^&#39; . $e . &#39;(.*)&#39; . $e . &#39;$/s&#39;, &#39;$1&#39;, $_csv_data[$_csv_i]);
       $_csv_data[$_csv_i] = str_replace($e . $e, $e, $_csv_data[$_csv_i]);
   }
   return empty ($_line) ? false : $_csv_data;
}
Copy after login
