This document discusses the Symfony framework and its components. It introduces the Symfony philosophy of being easy for newcomers and flexible for advanced users. It then summarizes several Symfony components like CssSelector, DomCrawler, Finder, and the HttpKernel interface. It concludes by asking if there are any questions.

2. The Symfony2 Philosophy

3. Be as easy as possible for newcomers
and as flexible as possible for advanced users

4. SymfonyComponents
SymfonyFramework

5. CssSelector

6. use SymfonyComponentsCssSelectorParser;
Parser::cssToXpath('h4 > a:contains("foo")');

7. use SymfonyComponentsCssSelectorParser;
$document = new DOMDocument();
$document->loadHTMLFile('...');
$xpath = new DOMXPath($document);
$expr = Parser::cssToXpath('a.smart');
$nodes = $xpath->query($expr);
foreach ($nodes as $node)
{
printf("%s (%s)n", $node->nodeValue, $node-
>getAttribute('href'));
}

8. DomCrawler

9. use SymfonyComponentsDomCrawlerCrawler;
$crawler = new Crawler($html);

10. addContent()
addHtmlContent()
addXmlContent()
addDocument()
addNodeList()
addNodes()
addNode()
add()

11. filter()
filterXpath()
eq()
reduce()
first() / last()
siblings()
nextAll() / previousAll()
parents() / children()

12. $link = $crawler->filter("h1 > h2");
$link = $crawler->filter("h1")->eq(1);

13. isEmpty()
each()
attr()
text()
extract()

14. $crawler
->filter('a.smart')
->each(function ($node)
{
print $node->getAttribute('href')."n";
});

15. $crawler
->filter('a')
->extract(array('_text', 'href'))
;

16. selectLink() / selectButton()

17. $crawler->selectLink("Greet Lucas");

18. $crawler->selectButton('submit');

19. $crawler->filter('a:contains("Greet")')->eq(1);

20. $link = $crawler
->selectLink("Greet Lucas")
->link();

21. $form = $crawler->filter(
'button:contains("submit")')->form();

22. // fill an input field
$form['name'] = 'Lucas';
// select an option or a radio
$form['country']->select('France');
// tick a checkbox
$form['like_symfony']->tick();
// upload a file
$form['photo']->upload('/path/to/lucas.jpg');

23. $form->getValues() / $form->getFiles()
array('article[title]' => 'Title', ...)
$form->getPhpValues() / $form->getPhpFiles()
array('article' => array('title' =>
'Title', ...))

24. Browser

25. http://www.github.com/fabpot/Goutte

26. Finder

27. use SymfonyComponentsFinderFinder;
$finder = new Finder();
$finder
->files()
->in(__DIR__)
->...()
->sortByName()
;

28. $finder
->name('*.php')
->depth('<= 1')
->date('>= yesterday')
->size('<= 1K')
->filter(function (SplFileInfo $file) {
return strlen($file->getBasename()) < 9;
})
;

29. foreach ($finder as $file) {
print $file->getRealpath()."n";
}
$files = iterator_to_array($finder);
$count = iterator_count($finder);

30. use SymfonyComponentsFinderFinder;
$s3 = new Zend_Service_Amazon_S3($key, $sct);
$s3->registerStreamWrapper("s3");
$finder = new Finder();
$finder
->name('photos*')
->size('< 100K')
->date('since 1 hour ago')
->in('s3://bucket-name')
;

31. HttpKernel: The framework construction kit

32. namespace SymfonyComponentsHttpKernel;
interface HttpKernelInterface
{
const MASTER_REQUEST = 1;
const FORWARDED_REQUEST = 2;
const EMBEDDED_REQUEST = 3;
public function handle(
Request $request = null,
$type = self::MASTER_REQUEST,
$raw = false);
public function getRequest();
}
