I'm trying to code a function in PHP to export some data to Excel file. The problem is if I save it to the server it does work, but if I try to send to the browser using php://output it just doesn't work. It doesn't even show the download window. I' ve been getting these as response:
PK����a�B%���a��������[Content_Types].xml͔]K�0���%��f� "�v��R���kX�����m��+����4�<�'��2�jgs6�,+��v����Sz���a�����tr5^�=Bb�9+c����,��9��.T"�kXr/�J,���[.��`ck6�?h�\��,���ܠ}3�c�C+��9�-E��|c�j�BKPN�+�d��u��O1� o��Ba +���G
Here's my code:
<?php
error_reporting(E_ALL);
ini_set('display_errors', TRUE);
ini_set('display_startup_errors', TRUE);
date_default_timezone_set('Europe/Rome');
require_once 'Classes/PHPExcel.php';
/** PHPExcel_IOFactory */
include 'Classes/PHPExcel/IOFactory.php';
$target ='templates/';
$fileType = 'Excel2007';
$InputFileName = $target.'richiesta.xlsx';
$OutputFileName = $target .'Richiesta_'.$_SESSION['User'].'_'.$_SESSION['Last'].'_'.$dat.'.xlsx';
//Read the file (including chart template)
$objReader = PHPExcel_IOFactory::createReader($fileType);
//$objReader->setIncludeCharts(TRUE);
$objPHPExcel = $objReader->load($InputFileName);
//Change the file
$objPHPExcel->setActiveSheetIndex(0)
// Add data
->setCellValue('C3','10' )
->setCellValue('C4','20' )
->setCellValue('C5','30')
->setCellValue('C5','40' );
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, $fileType);
//$objWriter->save($OutputFileName); //This one WORKS FINE!!!

$objWriter->save('php://output'); //NOT WORKING :-(
