How to use PHPExcel correctly with Symfony 2

问题:

I need to use PHPExcel with a Symfony2 project. Anyone know how to set up the project correctly to use the library? Should i put it in the vendor directory? What should be changed in the configuration files etc?

回答1:

If you are using composer to manage your project, you can just change the composer.json file:

"autoload": {
    "psr-4": {
        "": "src/",
        "": "vendor/phpoffice/phpexcel/Classes/"
    },
    "classmap": [
        "app/AppKernel.php",
        "app/AppCache.php"
    ]
},

Then add

use PHPExcel;
use PHPExcel_IOFactory;

to your controller file, and you can use the PHPExcel like this:

$objPHPExcel = new PHPExcel();

Hope it helps.

Actually, to do it right you need to follow next steps:

• Edit your deps file and add dependency from the PHPExcel

[PHPExcel]
git=http://github.com/PHPOffice/PHPExcel.git
target=/phpexcel
version=origin/master

• Run php bin/vendors install in order to install all missing dependencies (PHPExcel in our case)

• Update prefixes section in app/autoload.php:

$loader->registerPrefixes(array(
    // ...
    'PHPExcel'         => __DIR__.'/../vendor/phpexcel/Classes',
));

• Done. Now, you can use it in your bundle's controller (code based on PHPExcel example from Tests/01simple-download-xls.php):

<?php
namespace Demo\MyBundle\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Response;
use PHPExcel;
use PHPExcel_IOFactory;

class DemoController extends Controller
{
   public function demoAction()
   { 
       $response = new Response();

       // Create new PHPExcel object
       $objPHPExcel = new PHPExcel();

       // Set document properties
       $objPHPExcel->getProperties()->setCreator("Me")
                   ->setLastModifiedBy("Someone")
                   ->setTitle("My first demo")
                   ->setSubject("Demo Document");
       // Add some data
       $objPHPExcel->setActiveSheetIndex(0)
                   ->setCellValue('A1', 'Hello')
                   ->setCellValue('B2', 'world!')
                   ->setCellValue('C1', 'Hello')
                   ->setCellValue('D2', 'world!');
       // Set active sheet index to the first sheet
       $objPHPExcel->setActiveSheetIndex(0);

       // Redirect output to a client’s web browser (Excel5)
       $response->headers->set('Content-Type', 'application/vnd.ms-excel');
       $response->headers->set('Content-Disposition', 'attachment;filename="demo.xls"');
       $response->headers->set('Cache-Control', 'max-age=0');
       $response->prepare();
       $response->sendHeaders();
       $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
       $objWriter->save('php://output');
       exit();
   }
}

1. Copy the library to your vendors directory.

2. Configure autoloader in your bootstrap file:

   $loader->registerPrefixes(array(
       // Swift, Twig etc.
       'PHPExcel' => __DIR__ . '/../vendor/phpexcel/lib/PHPExcel'
   ));
   

3. That's all.

actually the best solution is to use https://github.com/liuggio/ExcelBundle. I tried to use @Crozin's solution but I was still getting an error about IOFactory::createWriter. Hope this helps, Simone

回答5:

As of Symfony 2.3, you can now do this:

...
"require": {
    ...
    "phpoffice/phpexcel": "dev-master"
    ...
},
...

Then just run composer update and dependencies will resolve automatically.

Or you can do composer require phpoffice/phpexcel:dev-master if you don't want to mess with the composer.json file.

回答6:

With composer (since Symfony2.1) it's really easy, you only have to modify the composer.json.
You don't need to register the namespace anymore!

Only two things, to notice:

1. refer to github tags, I only found a soltion with the package type
2. when changing something in the composer.json related to the class autoloading stuff, you have to remove the whole directory in the vendor dir
