To downloads symfony, you need to download symfony.phar(a small file PHP) from this link.

要下载 symfony，您需要symfony.phar从此链接下载（一个小文件 PHP）。

• Then, you have to move in your usual Web directory C:\wamp\www on windowsand /var/www on Linux;

• Execute php symfony.phar new project_name_and_versionfor example : symfony.phar new symfony2.8to download Symfony 2.8.

  Then, you can :

• Change your current directory to /var/www/html/project_name on Linuxor C:\wamp\www on windows;

• Configure your application in app/config/parameters.ymlfile ;

• And (always) read the documentation at http://symfony.com/doc.

• 然后，您必须进入您常用的 Web 目录C:\wamp\www on windows和/var/www on Linux;

• 执行php symfony.phar new project_name_and_version例如：symfony.phar new symfony2.8下载Symfony 2.8。

  然后你可以 ：

• 将当前目录更改为/var/www/html/project_name on Linux或 C:\wamp\www on windows;

• 在app/config/parameters.yml文件中配置您的应用程序；

• 并且（总是）阅读http://symfony.com/doc 上的文档。

Good luck ^^ !

祝你好运^^！

You need to install composer before. From your command line:

您需要先安装composer。从您的命令行：

php -r "readfile('https://getcomposer.org/installer');" > composer-setup.php
php -r "if (hash('SHA384', file_get_contents('composer-setup.php')) === '7228c001f88bee97506740ef0888240bd8a760b046ee16db8f4095c0d8d525f2367663f22a46b48d072c816e7fe19959') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
php composer-setup.php
php -r "unlink('composer-setup.php');"

The recommanded way to install Symfony is through a command, named symfony.

安装 Symfony 的推荐方法是通过名为symfony.

Read the docs from the official symfony website: http://symfony.com/doc/current/book/installation.html, for more info.

从官方 symfony 网站阅读文档：http: //symfony.com/doc/current/book/installation.html，了解更多信息。

So,

所以，

• If you are using MAC/Linux: http://symfony.com/doc/current/book/installation.html#linux-and-mac-os-x-systems

• $ cd /var/www/

• $ symfony new my_project_name(more readable example: $ symfony new Blog). This will create a directory (named Blog) inside your /var/www/directory, where all the code will be housed.

• 如果您使用的是 MAC/Linux：http: //symfony.com/doc/current/book/installation.html#linux-and-mac-os-x-systems

• $ cd /var/www/

• $ symfony new my_project_name（更易读的例子：）$ symfony new Blog。这将Blog在您的/var/www/目录中创建一个目录（名为），所有代码都将存放在该目录中。

Then you can install composer, as the official docs says, and use it for installing packages inside your Symfony project.

然后你可以安装composer，正如官方文档所说，并使用它在你的 Symfony 项目中安装包。

Happy coding!

快乐编码！

I tried this one:

我试过这个：

php symfony.phar new symfony2.8

The results is this

结果是这样的

[RuntimeException]
The Symfony Installer is not compatible with Symfony 4.x or newer versions.
Run this other command to install Symfony using Composer instead:
composer create-project symfony/skeleton symfony2.8

I tried the suggested command and it start download and install automatically

我尝试了建议的命令，它开始自动下载并安装

composer create-project symfony/skeleton symfony2.8
