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/控制台——版本(对于Symfony3: bin/console——版本)，它应该给你一个不错的主意。对于我的一个随机项目，输出为:

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，请尝试读取symfony/src/ symfony/ Component/HttpKernel/Kernel。php，其中的版本是硬编码的，例如:

const VERSION         = '2.2.0';

Just in case you are wondering, console creates an instance of Symfony\Bundle\FrameworkBundle\Console\Application. In this class constructor, it uses Symfony\Component\HttpKernel\Kernel::VERSION to initialize its parent constructor.

如果您想知道，控制台将创建Symfony\Bundle\FrameworkBundle\应用程序的实例。在这个类构造函数中，它使用Symfony\组件\HttpKernel::VERSION来初始化父构造函数。

Another way is to look at the source for Symfony\Component\HttpKernel\Kernel for where const VERSION is defined. Example on GitHub

另一种方法是查看定义const版本的Symfony\组件\HttpKernel内核的源代码。在GitHub的例子

Locally this would be located in vendor/symfony/symfony/src/Symfony/Component/HttpKernel/Kernel.php.

在本地这将位于供应商/symfony/symfony/src/ symfony/ Component/HttpKernel/Kernel.php。

#3

If you want to dynamicallly display your Symfony 2 version in pages, example in footer, you do can it this way.

如果您想动态地在页面中显示Symfony 2版本，例如在页脚中，您可以这样做。

create a service

创建一个服务

<?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;
}
}

注册在service.yml

 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

你可以在任何地方叫它。在Controller中，使用JSON或页面示例脚注包装它

 <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 updated in your template.I know this is overkill but this how I do it in my projects and it is working

现在，每当您运行composer update来更新供应商时，symfony版本也会在您的模板中自动更新。我知道这有点过头了，但我在我的项目中就是这么做的

we can find the symfony version using Kernel.php file but problem is the Location of Kernal Will changes from version to version (Better Do File Search in you Project Directory)

我们可以使用内核找到symfony版本。php文件，但问题是Kernal的位置会随着版本而变化(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\ \symfony\ \组件\ http\ Kernel.php

Check from Controller/ PHP File

从控制器/ PHP文件中检查

$symfony_version = \Symfony\Component\HttpKernel\Kernel::VERSION;
echo $symfony_version; // this will return version; **o/p:3.0.4-DEV**

#5

if you trying with version symfony

如果你尝试版本symfony

please try with

请试一试

symfony 2 +

cmd>php app/console --version

cmd > php应用程序/控制台版本

symfony 3+

symfony 3 +

cmd>php bin/console --version

cmd > php bin /控制台——版本

for example

例如

D:project>php bin/console --version

D:项目> php bin /控制台版本

Symfony 3.2.8 (kernel: app, env: dev, debug: true)

#6

also you can check the version of symfony and versions of all other installed packages by running

您还可以通过运行检查symfony的版本和所有其他已安装包的版本

composer show

或

composer show | grep sonata

to get versions of specific packages like sonata etc.

获取特定包的版本，如奏鸣曲等。

#7

if you are in app_dev, you can find symfony version at the bottom left corner of the page

如果您在app_dev中，可以在页面的左下角找到symfony版本

#8

From inside your Symfony project, you can get the value in PHP this way:

在Symfony项目中，可以通过以下方式获取PHP的值:

$symfony_version = \Symfony\Component\HttpKernel\Kernel::VERSION;

#9

For Symfony 3.4

Symfony 3.4

Check the constant in this file vendor/symfony/http-kernel/Kernel.php

检查这个文件供应商/symfony/http-kernel/Kernel.php中的常量。

const VERSION = '3.4.3';

或

composer show | grep symfony/http-kernel
