回答by Diego Agulló
Run app/console --version(for Symfony3: bin/console --version), it should give you a pretty good idea. On a random project of mine, the output is:
运行app/console --version（对于 Symfony3: bin/console --version），它应该会给你一个很好的主意。在我的一个随机项目中，输出是：
Symfony version 2.2.0-DEV - app/dev/debug
If you can't access the console, try reading symfony/src/Symfony/Component/HttpKernel/Kernel.php, where the version is hardcoded, for instance:
如果您无法访问控制台，请尝试阅读symfony/src/Symfony/Component/HttpKernel/Kernel.php，其中版本是硬编码的，例如：
const VERSION = '2.2.0';
Just in case you are wondering, consolecreates an instance of Symfony\Bundle\FrameworkBundle\Console\Application. In this class constructor, it uses Symfony\Component\HttpKernel\Kernel::VERSIONto initialize its parent constructor.
以防万一你想知道，console创建一个Symfony\Bundle\FrameworkBundle\Console\Application. 在此类构造函数中，它用于Symfony\Component\HttpKernel\Kernel::VERSION初始化其父构造函数。

Another way is to look at the source for Symfony\Component\HttpKernel\Kernelfor where const VERSIONis defined. Example on GitHub
另一种方法是查看定义Symfony\Component\HttpKernel\Kernelwhere的来源const VERSION。GitHub 上的示例
Locally this would be located in vendor/symfony/symfony/src/Symfony/Component/HttpKernel/Kernel.php.
在本地，这将位于vendor/symfony/symfony/src/Symfony/Component/HttpKernel/Kernel.php.

Although there are already many good answers I'd like to add an option that hasn't been mentioned. Using the command:
尽管已经有很多好的答案，但我想添加一个尚未提及的选项。使用命令：
php bin/console about
you can get many details about the current project. The first section is about Symfony itself and looks like this:
您可以获得有关当前项目的许多详细信息。第一部分是关于 Symfony 本身的，看起来像这样：
-------------------- -------------------------------------------
Symfony
-------------------- -------------------------------------------
Version 4.2.3
End of maintenance 07/2019
End of life 01/2020

I find the other information besides the version number very useful.
我发现除了版本号之外的其他信息非常有用。
There are also other sections providing details about the (framework) Kernel, PHP, Environment.
还有其他部分提供有关（框架）内核、PHP、环境的详细信息。

Use the following command in your Terminal/Command Prompt:
在终端/命令提示符中使用以下命令：
php bin/console --version
This will give you your Symfony Version.
这会给你你的 Symfony 版本。

If you want to dynamicallly display your Symfony 2 version in pages, for example in footer, you can do it this way.
如果你想在页面中动态显示你的 Symfony 2 版本，例如在页脚中，你可以这样做。
Create a service:
创建服务：
<?php
namespace Project\Bundle\DuBundle\Twig;
class SymfonyVersionExtension extends \Twig_Extension
{
public function getFunctions()
{
return array(
//this is the name of the function you will use in twig
new \Twig_SimpleFunction('symfony_version', array($this, 'b'))
);
}
public function getName()
{
//return 'number_employees';
return 'symfony_version_extension';
}
public function b()
{
$symfony_version = \Symfony\Component\HttpKernel\Kernel::VERSION;
return $symfony_version;
}
}
Register in service.yml
在 service.yml 中注册
dut.twig.symfony_version_extension:
class: Project\Bundle\DutBundle\Twig\SymfonyVersionExtension
tags:
- { name: twig.extension }
#arguments: []
And you can call it anywhere. In Controller, wrap it in JSON, or in pages example footer
你可以在任何地方调用它。在 Controller 中，将其包装在 JSON 中，或在 pages 示例页脚中
<p> Built With Symfony {{ symfony_version() }} Version MIT License</p>
Now every time you run composer update to update your vendor, symfony version will also automatically update in your template.I know this is overkill but this is how I do it in my projects and it is working.
现在每次你运行 composer update 来更新你的供应商时，symfony 版本也会在你的模板中自动更新。我知道这有点矫枉过正，但这就是我在我的项目中这样做的方式并且它正在工作。

also you can check the version of symfony and versions of all other installed packages by running
您也可以通过运行来检查 symfony 的版本和所有其他已安装软件包的版本
composer show
or
或者
composer show | grep sonata
to get versions of specific packages like sonata etc.
获取特定软件包的版本，如奏鸣曲等。

we can find the symfony version using Kernel.phpfile but problem is the Location of Kernal Will changes from version to version (Better Do File Search in you Project Directory)
我们可以使用Kernel.php文件找到 symfony 版本，但问题是 Kernal Will 的位置随着版本的变化而变化（最好在项目目录中进行文件搜索）
in symfony 3.0 : my_project\vendor\symfony\symfony\src\Symfony\Component\HttpKernel\Kernel.php
在 symfony 3.0 中：my_project\vendor\symfony\symfony\src\Symfony\Component\HttpKernel\Kernel.php
Check from Controller/ PHP File
从控制器/ PHP 文件检查
$symfony_version = \Symfony\Component\HttpKernel\Kernel::VERSION;
echo $symfony_version; // this will return version; **o/p:3.0.4-DEV**

From inside your Symfony project, you can get the value in PHP this way:
从您的 Symfony 项目内部，您可以通过以下方式在 PHP 中获取值：
