Good afternoon for all, I'm generating an XLS and a PDF with PHPExcel in my development environment works perfect, but when publish the application in the server, the system generates the file but when I open file generated with 1K in size I get an error saying the file does not match the format or is damaged, what can ido? the code that generates the PDF is:


//Traemos las librerias necesarias

Raxan::loadConfig('../config.php'); // load external config file
Raxan::config('site.timezone','America/Toronto'); // set timezone

class NewPage extends RaxanWebPage {

protected $db;

protected function _config() {
$this->degradable = true;
// enable or disable debugging
$this->Raxan->config('debug', false);
try {
$this->db = $this->Raxan->connect('booking'); // connect to db
catch (Exception $e) {
$this->db = null;
$msg = $this->getView('connection-failed.html');
$this->flashmsg($msg,'bounce','rax-box error');


protected function _init() {
$idR = $this->get->intVal('idReserva'); 
$sql ='SELECT sum(totFulles) as tf, sum(totPiezas) as tp, sum(peso) as tps

$tp = (int)$rows[0]['tp'];

Open the bad file with a text editor, examine the file of php errors that should store your server. You should find clues for the problem
Recent PHPExcel versions don't include the pdf library (in return, you have the choice). Do you have the same version in dev' and prod'? The pdf library is present on production server? Problem of write (temporary file) on a machine with a more strict configuration ? Etc.
