PHP Streaming CSV always adds UTF-8 BOM
- by Mustafa Ashurex
The following code gets a 'report line' as an array and uses fputcsv to tranform it into CSV. Everything is working great except for the fact that regardless of the charset I use, it is putting a UTF-8 bom at the beginning of the file. This is exceptionally annoying because A) I am specifying iso and B) We have lots of users using tools that show the UTF-8 bom as characters of garbage.
I have even tried writing the results to a string, stripping the UTF-8 BOM and then echo'ing it out and still get it. Is it possible that the issue resides with Apache?
If I change the fopen to a local file it writes it just fine without the UTF-8 BOM.
header("Content-type: text/csv; charset=iso-8859-1");
header("Cache-Control: no-store, no-cache");
header("Content-Disposition: attachment; filename=\"report.csv\"");
$outstream = fopen("php://output",'w');
for($i = 0; $i < $report-rowCount; $i++)
{
fputcsv($outstream, $report-getTaxMatrixLineValues($i), ',', '"');
}
fclose($outstream);
exit;
