在excel中以正确的编码导出UTF-8数据

Posted 2021-02-24

If you want to export some utf-8 data into csv/tsv that will be readable by excel with correct encoding you must add special non vissable characters at the begining of file

<?php 
 
$data = "Some utf-8 characters ąćżźćł" 
 
header("Content-Type: application/octet-stream"); 
header("Content-Transfer-Encoding: binary"); 
header('Expires: '.gmdate('D, d M Y H:i:s').' GMT'); 
header('Content-Disposition: attachment; filename = "Export '.date("Y-m-d").'.tsv"'); 
header('Pragma: no-cache'); 
 
//these characters will make correct encoding to excel 
echo chr(255).chr(254).iconv("UTF-8", "UTF-16LE//IGNORE", $data); 
 
?>
