今天碰到網站利用IE下載檔案時發生無法辨識檔名與檔案類型
花了一點時間找問題來源，原來是IE讀 http header 讀到uft-8的編碼時會有問題
只好針對IE多寫一個判斷，讓程式偵測到瀏覽器為IE時把檔名轉碼
function dl_file( $file ){
if ( file_exists($file) ) {
$filename = basename($file);
}
// 若為IE瀏覽器則將檔名編碼轉換成Big5
if ( strpos( $_SERVER['HTTP_USER_AGENT'], "MSIE" ) ) {
$filename = iconv('utf-8', 'big5', $filename);
}
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.$filename);
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: '.filesize($file) );
ob_clean();
flush();
readfile($file);
exit;
} else {
echo "Error: File not found.";
return false;
}
