There’s a reason for the challenge. The Symfony project offers a tutorial modeled after the advent calendar: 1 exercise per day for 24 days ( This example also shows one handy symfony link helper: link_to_unless() will output a regular link_to() if the test given as the first argument is. A lot of developers learned symfony thanks to askeet, and many companies still use askeet as their main training material. But the askeet tutorial started to show.

Jobeet – Day 1: Starting up the Project (Symfony Blog)
December 1, Fabien Potencier. The symfony framework has been an Open-Source project for more than three years and has become one of the most popular PHP frameworks thanks to its great features and great documentation. And this grand tradition started early on. In Decemberjust after the first official release of symfony, we published the ” Askeet tutorial “, a set of 24 tutorials, published day-by-day between December 1st and Christmas.
This tutorial has proven to be an invaluable tool to promote the framework to newcomers. A lot of developers learned symfony thanks to askeet, and many companies still use askeet as their main training material.
We are now celebrating the release of symfony 1. So, it’s time for another fresh tutorial. That’s right, we will do it again. Every day including week-ends, a new tutorial will be published. Each askee is meant to last about one hour, and will be the occasion to learn symfony by coding a real website, from start to finish.
One hour times twenty-four equals a day, and that’s exactly how long we think that a developer needs to learn the fundamentals of symfony. Every day, new features will be added to the application, and we’ll take advantage of this development to introduce you to new symfony functionalities as well as good practices in symfony web development.
Aseket askeet, the 21st day was the “get-a-symfony-guru-for-a-day”. We had no plan, and the community had to propose a feature to add to askeet. It was a great success and the community decided that we needed a search engine to the application. And we did it. The 21st day tutorial also proved to be one of the most popular of the askeet tutorials. For Jobeet, we will celebrate the winter on the 21st with tuhorial “design day”.
So, if you work with a designer, or if your company has a design department, you will be able tutoral contribute a design. On the 21st, we will organize a poll and the community will have to choose the default tutorual that will be bundled with Jobeet. You will of course receive credits and all the fame associated with it!
Remember the early days of PHP4. Ah, la Belle Epoque! PHP was one of the first languages dedicated to the web and one askfet the easiest to learn. Ttutorial as web technologies evolve at a very fast pace, web developers need to keep up with the latest best practices and tools.
The best way to learn is of course by reading blogs, tutorials, and books. We have read a lot of these, be they written for PHP, Python, Java, Ruby, or Perl, and many of them fall short when the author starts giving snippets of codes as examples. These things are serious business. They are perhaps the most important part of any piece of code. And askeeg a reader, you are left alone.
Without these concerns taken into account, the examples are much less useful. You cannot use them as a good starting point. Because security, validation, error handling, and tests, just to name a asskeet, take care to code right. In this tutorial, you will never see statements like those as we will write tests, error handling, validation code, and be sure we develop a secure application.
That’s because symfony is about code, but also about best practices hutorial how to develop professional applications for the enterprise. We will be able to afford this luxury because symfony provides all the tools needed to code these aspects easily without writing too much code.
Jobeet – Day 1: Starting up the Project
Validation, error handling, security, and tests are first-class citizens tutorrial symfony, so it won’t take us too long to explain. This is just one of many reasons why to use a framework for “real life” projects. All the code you will read in this tutorial is code you tutoriwl use for a real project.
We encourage you to copy and paste snippets of code or steal whole chunks. The application to be designed could have been yet another blog engine. But we want to use symfony on a useful project. The goal is to demonstrate that symfony can be used to develop professional applications with style and little effort. We will keep the content of the project secret for another day as we already have much to do today. However, you already know the name of the application: As 24 hours is plenty of time to develop an application with symfony, we won’t write PHP code today.
But even without writing a single line of code, you will start understanding the benefits of using a framework like symfony, just by bootstrapping a new project. The objective of the day is to setup the development environment and display a page of the application in a web browser. This includes installation of symfony, creation of an application, and web server configuration.
As we will use the command line a lot, it’s better to use a Unix-like OS, but if you run a Windows system, it will also work fine, you’ll just have to tutoorial a few commands in the cmd prompt. Unix shell commands can come in handy in a Windows environment. If you would like to use tools like targzipor grep on Windows you can install Cygwin.
The official docs are a little sparse, so a good installation guide can be found here. The adventurous may also like to try Microsoft’s Windows Asmeet for Unix. As this tutorial will mostly focus on the symfony framework, we will assume that you already have a solid knowledge of PHP 5 and Object Oriented programming.
Windows users are advised to run symfony and to setup their new project in a path which contains no spaces. Avoid using the Documents and Settings directory, including anywhere under My Documents. To install symfony, download the archive package found on the symfony website.
As this tutorial has been written for symfony 1. Under the “Source Download” section, you will find the archive in the. Under Windows unzipping the zip file can be done with the explorer. After you renamed the directory to symfonythere should be a directory named c: As PHP configurations vary a lot from a distribution to another, we need to check that your PHP configuration meets tutrial symfony minimum requirements.
Launch the configuration checker script provided with symfony from the command line:. If there is a problem, the output will give you hints on how to fix it. You should also execute the checker from a tutroial as PHP configuration can be different. Copy the file somewhere under the web server root directory and access the file.
Don’t forget to remove the file from the web root directory afterwards. If the script does not output any error, check that symfony is correctly installed by using the symfony command line to display the version note the capital V:. If you are curious about what this command line tool can do for you, type symfony to list the available options and tasks:.
The symfony command line is the developer best friend. It provides a lot of utilities that improve your productivity for day-to-day activities like cleaning the cache, generating code, and much more.
In symfony, applications sharing the same data model are regrouped into projects. For the Jobeet project, we will have two different applications: From the jobeet directory, run the symfony generate: Why does symfony generate so many files? One of the main benefits of using a full-stack framework is to standardize your developments. Thanks to symfony default structure of files and directories, any developer with some symfony knowledge can take over the maintenance of any symfony project.
In a matter of minutes, he will be able to dive into the code, fix bugs, and add new features. So, from now on, instead of using the fully qualified path to the symfony program, we will use the symfony shortcut.
As the symfony file is executable, Unix users tutoorial replace all occurrences of ‘php symfony’ by ‘. On Windows you can copy the ‘symfony.
Once again, the generate: All symfony commands must be run in the project root directory unless explicitly said otherwise. When calling the generate: By passing these two optional options to the tutoril, we have secured our future development from the two most widespread vulnerabilities found on the web.

That’s right, symfony will automatically take security measures on our behalf. That way, you can move the Jobeet project directory anywhere on your machine or another one, and it will just work. These files are called front controllers: But why do we have two front controllers as we have only defined one application? Both files point to the same application but for different environments.
When you develop an application, except if you develop directly on the production server, you need several environments:. What makes an environment unique? In the development environment, the application needs to log all the details of a request to ease the debugging, it must display exception in the browser, but the cache system must be disabled as all changes made to the code must be taken into account right away. So, the development environment must be optimized for the developer:.
But on the production environment, the application must display customized error messages instead of raw exceptions, and of course, the cache layer must be activated. So, the production environment must be optimized for performance and the user experience. A symfony environment is a unique set of configuration settings and symfony comes bundled with three of them:
