tu ferais pas un include du fichier après une sortie HTML ou un echo ?
y a pas d'espace avant le <? ?
donne le code du fichier à partir du début jusqu'à l'inclusion stp.

Bonjour,
j'utilise sur mon serveur web le script de Biff qui permet de créer facilement un fichier Excel (.xsl). J'ai déjà regardé dans la doc, voici mon code :
<?
include "biff.php";
$myxls = new BiffWriter();
$myxls->outfile = 'monficher.xls';
//les differents champs
$myxls->xlsWriteText(0,0,"Date" );
$myxls->xlsWriteText(0,1,"Sessions" );
$myxls->xlsWriteText(0,2,"Pages" );
$myxls->xlsParse();
?>
Il me sort une erreur:
Warning: Cannot add header information - headers already sent by (biff.php:321) in biff.php on line 206
Je regarde et effectivement il fait ceci:
header("Expires: Mon, 1 Apr 1974 05:00:00 GMT" );
header("Last-Modified: " . gmdate("D,d M YH:i:s" ) . " GMT" );
header("Cache-Control: no-cache, must-revalidate" );
header("Pragma: no-cache" );
header("Content-Disposition: attachment; filename=$this->outfile\r\n\r\n" );
header("Content-Type: application/octet-stream" );
Pourtant, je ne fais pas de echo ou autre dans mon fichier php. Quelqu'un pourrait-il m'aider siouplé
