This section provides an overview of what symfony3 is, and why a developer might want to use it.
It should also mention any large subjects within symfony3, and link out to the related topics. Since the Documentation for symfony3 is new, you may need to create initial versions of those related topics.
3. Windows Systems
You must add php to your path environment variable. Follow theses steps :
Windows 7 :
- Right-click on a My Computer icon
- Click Properties
- Click Advanced system settings from the left nav
- Click Advanced tab
- Click Environment Variables button
- In the System Variables section, select Path (case-insensitive) and click Edit button
- Add a semi-colon (;) to the end of the string, then add the full file system path of your PHP installation (e.g.
- Keep clicking OK etc until all dialog boxes have disappeared
- Close your command prompt and open it again
Windows 8 & 10
- In Search, search for and then select: System (Control Panel)
- Click the Advanced system settings link.
- Click Environment Variables.
- In the section System Variables, find the PATH environment variable and select it. Click Edit. If the PATH environment variable does not exist, click New.
- Add the full file system path of your PHP installation (e.g.
After this, open your command console and execute the following command:
c:\> php -r "readfile('https://symfony.com/installer');" > symfony
Then, move the downloaded symfony file to your project’s directory and execute it as follows:
c:\> move symfony c:\projects c:\projects\> php symfony
4. Creating the Symfony Application
Once the Symfony Installer is available, create your first Symfony application with the new command:
# Linux, Mac OS X $ symfony new my_project_name # Windows c:\> cd projects/ c:\projects\> php symfony new my_project_name
This command can be run from anywhere, not necessarily from the
This command creates a new directory called
my_project_name/ that contains a fresh new project based on the most recent stable Symfony version available. In addition, the installer checks if your system meets the technical requirements to execute Symfony applications. If not, you’ll see the list of changes needed to meet those requirements.
1. Installing the Symfony Installer
The installer requires PHP 5.4 or higher. If you still use the legacy PHP 5.3 version, you cannot use the Symfony Installer. Read the Creating Symfony Applications without the Installer section to learn how to proceed. - source: https://symfony.com/doc/current/book/installation.html
5. Basing your Project on a Specific Symfony Version
In case your project needs to be based on a specific Symfony version, use the optional second argument of the new command:
# use the most recent version in any Symfony branch $ symfony new my_project_name 2.8 $ symfony new my_project_name 3.1 # use a specific Symfony version $ symfony new my_project_name 2.8.1 $ symfony new my_project_name 3.0.2 # use a beta or RC version (useful for testing new Symfony versions) $ symfony new my_project 3.0.0-BETA1 $ symfony new my_project 3.1.0-RC1
The installer also supports a special version called lts which installs the most recent Symfony LTS version available:
$ symfony new my_project_name lts
Read the Symfony Release process to better understand why there are several Symfony versions and which one to use for your projects.
You can also create symfony applications without the installer, but it was not an good idea. If you want anyway, follow the original tutorial on this link:
2. Linux and Mac OS X Systems
Open your command console and execute the following commands:
$ sudo curl -LsS https://symfony.com/installer -o /usr/local/bin/symfony $ sudo chmod a+x /usr/local/bin/symfony
Simplest example in Symfony
Install symfony correctly as guided above.
Start symfony server if you are not installed in www directory.
Ensure https://localhost:8000 is working if symfony server is used.
Now it is ready to play with simplest example.
Add following code in a new file /src/AppBundle/Controller/MyController.php in symfony installation dir.
Test the example by visiting https://localhost:8000/hello
That’s all. Next: use twig to render the response.I\'m the response for request /hello
