Php 7 Allows Calling A \ Generator Country Email List Function From Another Class.

Post by diparani »

So our code might look like this: A repository that returns the list of our Cat entities use Doctrine\ORM\EntityRepository; class CatRepository extends EntityRepository { public function getCats(): \Generator { $results = $this->find(); foreach ($result as $cat) { yield $cat; } } } In another class ( controller, manager, service …) $listCats = function () use ($catRepository) { yield from $catRepository->getCats(); } foreach ($listCats() as $cat) { echo $cat->getName(); } Another example of using yield in Api Platform in the case of developing a custom data provider country email list collection . Rather than returning the country email list the data. Complements PHP provides 3 functions: iterator_apply : calls a function on all elements of an iterator; iterator_to_array : copies the country email list elements of the iterator into an array (); iterator_count: returns the number of elements in the iterator (caution, using this function may change the position of the current element). Conclusion Iterators and generators should be much clearer to you after reading. Their use will make it possible to have a more rigorous and more flexible code for the manipulation of lists of objects, but also to sweep away bad practices in the use of arrays. A thank you to Lazer, Bazoo, Nibbler and Kata who agreed to participate in this article, as well as to Jean-Baptiste and Lucie for proofreading.

The Web has changed a lot since its creation in 1989 by Tim Berners Lee. HTML prevailed. The processing of its rendering, carried out on the server side with languages ​​such as PHP, has become commonplace and has led to the rise of CMS , a simple solution to implement to deploy rich content sites in a minimum of steps. Today, the Web is country email list consumed on new terminals such as mobile phones or embedded systems. Current systems must evolve to adapt to the modes of access to their information. We don't have the same needs when surfing on a fixed computer or a connected fridge. It is from this observation that the appearance of the notion of decoupled web country email list architecture, called “ headless ” in English, arose. What does this anti-monarchist sounding term mean? What can we gain from this? How does it work with Drupal and how to easily implement it? This is what we will see in this article. What is Headless? It's an approach where the part responsible for the country email list model and controllers of an MVC pattern – the data set and its processing – is separated from the view – the display of the data. In our case, the CMS will act as the back-end , in which the contents are created.

The front-end is managed by another technology. The most common cases are using a JavaScript framework such as Vue.js or React . Figures 1 and 2 Figure 1 HeadlessFigure 2 Headless This approach has certain advantages . It allows you to use a technology originally intended for rendering, such as React. These technologies offer more flexibility country email list and can perform better depending on the use case. The break between the code and its presentation facilitates maintenance. It becomes clear which party manages what and therefore which team should be mobilized. We can see performance improvements, because the API will limit the country email list number of direct calls to the database, a key friction point in a web architecture. When should this architecture be considered? Specific need for the power of a front technology ; Several platforms will display the data: mobile, television, different web interfaces, etc. ; If the display needs to be particularly adaptable to the information it displays; If the content is consumed by many targets, the back office centralizing the data is a way to avoid content duplication.
