PHP生成CSV文件用Excel打开乱码问题

今天有一同学问我为什么PHP生成CSV文件用Excel打开会出现乱码呢,下面小编来给大家找了一些常见的办法,希望此方法对各位朋友会有所帮助。

百度查证后得知

PHP生成UTF-8编码的CSV文件用Excel打开中文显示乱码,是由于输出的CSV文件中没有BOM。

我们只要简单处理一下即可

那么如何在PHP中输出BOM呢?

在所有内容输出之前

 代码如下 复制代码

print(chr(0xEF).chr(0xBB).chr(0xBF));


例.php生成csv时我们可以这样

 代码如下 复制代码

$now = gmdate("D, d M Y H:i:s");
header("Expires: Tue, 03 Jul 2001 06:00:00 GMT");
header("Cache-Control: max-age=0, no-cache, must-revalidate, proxy-revalidate");
header("Last-Modified: {$now} GMT");
 
// force download
header("Content-Type: application/force-download");
header("Content-Type: application/octet-stream");
header("Content-Type: application/download");
 
// disposition / encoding on response body
header("Content-Disposition: attachment;filename={$filename}");
header("Content-Transfer-Encoding: binary");
$items_data=array(
'0'=>array('title'=>'test test test1'),
'1'=>array('title'=>'test test test2'),
'2'=>array('title'=>'test test test3')
)
print(chr(0xEF).chr(0xBB).chr(0xBF));//设置utf-8 + bom ,处理汉字显示的乱码
echo array2csv($items_data);
 
function array2csv(array &$array)
{
   if (count($array) == 0) {
     return null;
   }
   ob_start();
   $df = fopen("php://output", 'w');
   fputcsv($df, array_keys(reset($array)));
   foreach ($array as $row) {
      fputcsv($df, $row);
   }
   fclose($df);
   return ob_get_clean();
}
?>

还有一种办法就是使用Office

打开Microsoft Office 2010 Excel,数据-自文本,如图:

导入此csv格式文件,同样要求选择编码,如图:

  这里选择UTF-8,打开后,发现乱码消除,如图:

  补:UTF-8是在互联网上使用最广的一种unicode编码的实现方式。UTF-8最大的一个特点,就是它是一种变长的编码方式。它可以使用1~4个字节表示一个符号,根据不同的符号而变化字节长度
