i use php-export-data class excel output. class works on localhost , godady server on new server in doesn't work.
it gives header error. likes this.:
warning: cannot modify header information - headers sent (output started @ /home/mmm/public_html/head/adminsss/config.php:1) in /home/mmm/public_html/head/adminss/modules/head/class/php-export-data.class.php on line 489 warning: cannot modify header information - headers sent (output started @ /home/mmm/public_html/head/adminsss/config.php:1) in /home/mmm/public_html/head/adminsss/modules/head/class/php-export-data.class.php on line 490<br> line 489 => header("content-type: application/vnd.ms-excel; charset=" . $this->encoding); line 490 => header("content-disposition: inline; filename=\"" . basename($this->filename) . "\"");
- localhost php version 5.5.11
- godady php version 5.3.24
- new server php version 5.5.23
how can fix this?
if error message shows first line " /config.php:1 " , must convert php file without bom .
utf-8 bom linebreaks , spaces alone can problem. there "invisible" character sequences can cause this. famously utf-8 bom (byte-order-mark) isn't displayed text editors. it's byte sequence ef bb bf, optional , redundant utf-8 encoded documents. php has treat raw output. may show characters  in output (if client interprets document latin-1) or similar "garbage".
