I'm having a problem with my function. The purpose of my function is to force a string to be downloaded. What it really happens is that the string is outputted to the screen and not downloaded.

Bu benim fonksiyonudur:

function arrayToCSV($vectorDados, $cabecalho)
{
    $arr = array();
    $arr=$vectorDados;

    $csv = $cabecalho . "\n";
    foreach($arr as $row) {
    	$csv .=$row[0] . "	" .  $row[1] . "	". $row[2] . "	" .$row[3] . "	\n";
    }
    $filename = "emails_".date("Y-m-d_H-i",time());


    header ("Content-Type: application/octet-stream");
    header ("Content-disposition: attachment; filename=".$filename.".csv");
    print $csv;
}
