integrate PHPExcel withe ZendFramework 2 - php

Question

I try to use both libraries PHPWord and PHPExcel as two libraries in ZendFramework2
that is to say put them in /lib of Zend Framework 2 and load them into my controller with
in my autoload.php i put the following
<?php
// autoload.php generated by Composer
require_once __DIR__ . '/composer' . '/autoload_real.php';
return ComposerAutoloaderInit689ffe38af096b92264c8f237441d64e::getLoader();
require_once 'Zend/Loader/Autoloader.php';
$loader = Zend_Loader_Autoloader::getInstance();
$loader->autoloadernamespaces[] = "Excel_";
$loader->registerNamespace('Excel_');
$loader->setFallbackAutoloader(true);
if ($configSection == 'development')
{
$loader->suppressNotFoundWarnings(false);
}
my Controller is :
<?php
namespace Auth\Controller;
use Zend\Mvc\Controller\AbstractActionController;
use Zend\Excel\PHPExcel;
class AuthController extends AbstractActionController
{
public function LoginAction()
{
$objPHPExcel = new PHPExcel_Reader_Excel5();
$document = $objPHPExcel->load('example1.xls');
echo date('H:i:s') , " Données Ajoutées Avec Succés" ;
$document->setActiveSheetIndex(0)
->setCellValue('A1', 'Mike')
->setCellValue('D2', 'Spils);
// Save Excel5 file
$objWriter = PHPExcel_IOFactory::createWriter($document, 'Excel5');
$objWriter->save(str_replace('.php', '.xls', __FILE__));
}
}
`
but the classe is not being load
i get the following error
( ! ) Fatal error: Class 'Auth\Controller\PHPExcel_Reader_Excel5' not found in C:\wamp\www\zend\module\Auth\src\Auth\Controller\AuthController.php on line 14
any one can help me pleeeeaase ?

Answer 1

If you are using composer to load zendframework, try to load phpExcel lib too using composer.php.
Run following command from command line in project folder:
php composer.phar selfupdate
php composer.phar require phpoffice/phpexcel
Access in controller method as:
$excelObj = new \PHPExcel();
It works for me.

Answer 2

If you use the "classic" Skeleton
Download the library (in MyApp/vendor/library/ for example)
The website is : http://phpexcel.codeplex.com/
The architecture of PHPExcel is made with prefixes (like zf1), so for me, it's easier to use the "Zend\Loader\ClassMapAutoloader" like this :
modify the file autoload_classmap of your module
<?php
return array('PHPExcel'=>__DIR__.'/../../vendor/library/PhpExcel/PHPExcel.php',);
And so you can use :
$excel = new \PHPExcel();

Answer 3

I don't yet have any experience with ZF2. But I am pretty sure you're registering a wrong namespace, it should be:
$loader->autoloadernamespaces[] = "PHPExcel_";
$loader->registerNamespace('PHPExcel_');
EDIT
Do you have your PHPExcel library in Zend/Excel/PHPExcel at this location?
Well again I am not sure but, it shouldn't be placed inside Zend's core library.
use PHPExcel\Reader\Excel5;
It should be placed parallel to Zend's library perhaps.
- Zend/
- PHPExcel/
EDIT 2
If this is how Zendframework 2 folder structure is:
- vendor/
- zendframework/zendframework/library/Zend
- PHPExcel/
- autoload.php
Perhaps this should be the location to have your PHPExcel library I think

Answer 4

As suggested by #ro-ko, you should place the folder in vendor, so
vendor/PHPExcel
Then open up vendor/composer/autoload_namespaces.php
You'll see something like this
<?php
// autoload_namespaces.php generated by Composer
$vendorDir = dirname(__DIR__);
$baseDir = dirname($vendorDir);
return array(
'Zend\\' => $vendorDir . '/zendframework/zendframework/library/',
'ZendTest\\' => $vendorDir . '/zendframework/zendframework/tests/',
);
Simply add you namespace and the path to that array, eg...
return array(
'Zend\\' => $vendorDir . '/zendframework/zendframework/library/',
'ZendTest\\' => $vendorDir . '/zendframework/zendframework/tests/',
'PHPExcel\\' => $vendorDir . '/PHPExcel/',
);

Answer 5

This is what solved my problem in ZF2.
Added this to
/vendor/composer/autoload_namespaces:
'PHPExcel' => array($vendorDir . '/zendframework/zendframework/library/Zend/PHPExcel/'),
And in the controller instantiate the class:
$objPHPExcel = new \PHPExcel();

Answer 6

The problem is related to autoload PHPExcel classes. The vendor/autoload.php file it’s an auto-generated file. The implication is "don’t edit this file and expect your changes to stick".
In alternative, to avoid to have problems with autoload PHPExcel classes, is available an easy integration of PHPOffice/PHPExcel library into zend framework 2, using the zf2 module MvlabsPHPExcel.
After that you need to enable the MvlabsPHPExcel module:
<?php
return [
'modules' => [
// ...
'MvlabsPHPExcel',
],
// ...
];
And after that you be able to use inside the controller.
$phpExcelObject = $this->serviceLocator->get('mvlabs.phpexcel.service')->createPHPExcelObject();
