Hola beququi!!
Mira,para descargar archivos yo lo que hago es:
Código PHP:
<?php
$files_folder = "ruta";
$size = $files_folder;
if (detect_browser($HTTP_USER_AGENT) == "ie")
{
Header("Content-type: application/force-download");
}else{
Header("Content-Type: application/octet-stream");
}
Header("Content-Length: ".filesize($size));
Header("Content-Disposition: attachment; filename=nombre.extension");
readfile($size);
#########################################################################
function detect_browser($var)
{
if(eregi("(msie) ([0-9]{1,2}.[0-9]{1,3})", $var))
{
$c = "ie";
}else{
$c = "nn";
}
return $c;
}
?>
Espero que te sirva!!
