Question

在将symfony从2.3升级到2.7之后，我收到了许多弃用警告消息，我没有找到解决该问题的链接。

我收到的警告信息是：

DEPRECATED - The Twig_Function class is deprecated since version 1.12 and will be removed in 2.0. Use Twig_SimpleFunction instead.  -

有关您的信息，这是我正在使用的树枝版本：

php  composer.phar show -i | grep twig
twig/extensions                      v1.0.1             Common additional features for Twig that do not directly belong in core
twig/twig                            v1.22.1            Twig, the flexible, fast, and secure template language for PHP

NB。在我看来，弃用来自于我安装的一些捆绑包使用了一些不推荐使用的功能。所以，下面是composer.json文件，以防它可以提供帮助。

NB。我的Twig_Function_Method，Twig_Function_Node，...有类似的警告讯息。

NB。此link告诉我们有弃用但没有说明如何解决它们。

Answer 1

我发现捆绑包导致了我的弃用。要查找它们，只需通过以下命令查看包含单词public static void printCommonLogTable() { double x = 0.0; while (x <= 10.0) { System.out.println(x + " " + Math.log(x) + " "); x = x + 0.5; } }的文件：

Twig_Function_Method

结果如下：

grep --exclude-dir={'./app/cache/','./app/logs/'} -rnw '.' -e "Twig_Filter_Method"

总之，这些是导致我弃用的捆绑：./vendor/jms/translation-bundle/JMS/TranslationBundle/Twig/TranslationExtension.php:56: 'desc' => new \Twig_Filter_Method($this, 'desc'), ./vendor/jms/translation-bundle/JMS/TranslationBundle/Twig/TranslationExtension.php:57: 'meaning' => new \Twig_Filter_Method($this, 'meaning'), ./vendor/jms/serializer/src/JMS/Serializer/Twig/SerializerExtension.php:46: 'serialize' => new \Twig_Filter_Method($this, 'serialize'), ./vendor/nelmio/api-doc-bundle/Nelmio/ApiDocBundle/Twig/Extension/MarkdownExtension.php:22: 'extra_markdown' => new \Twig_Filter_Method($this, 'markdown', array('is_safe' => array('html'))), ./vendor/knplabs/knp-time-bundle/Knp/Bundle/TimeBundle/Twig/Extension/TimeExtension.php:46: 'ago' => new \Twig_Filter_Method($this, 'diff', array( ./vendor/twig/twig/doc/deprecated.rst:45: * ``Twig_Filter_Method`` ./vendor/twig/twig/doc/advanced_legacy.rst:707:You can also use ``Twig_Filter_Method`` instead of ``Twig_Filter_Function`` ./vendor/twig/twig/doc/advanced_legacy.rst:715: 'rot13' => new Twig_Filter_Method($this, 'rot13Filter'), ./vendor/twig/twig/doc/advanced_legacy.rst:727:The first argument of the ``Twig_Filter_Method`` constructor is always ./vendor/twig/twig/doc/advanced_legacy.rst:747: 'date' => new Twig_Filter_Method($this, 'dateFilter'), ./vendor/twig/twig/lib/Twig/Filter/Method.php:12:@trigger_error('The Twig_Filter_Method class is deprecated since version 1.12 and will be removed in 2.0. Use Twig_SimpleFilter instead.', E_USER_DEPRECATED); ./vendor/twig/twig/lib/Twig/Filter/Method.php:23:class Twig_Filter_Method extends Twig_Filter，jms/translation-bundle，nelmio/api-doc-bundle。

我将等待这些捆绑包得到更新。

我希望答案能帮助其他人。

Answer 2

我找到了这个帖子，因为我在更新树枝时遇到了同样的问题。

在日志中，您会找到以下行：

/logs/symfony/dev.log:7000:[2017-04-05 10:10:57] php.INFO: The Twig_Function_Node class is deprecated since version 1.12 and will be removed in 2.0. Use Twig_SimpleFunction instead.

也许这会帮助下一批到达这里的人。

只需替换：

'form_range' => new \Twig_Function_Node(...);

使用：

'form_range' => new \Twig_SimpleFunction(...),

如何解决Twig_Function，Twig_Function_Method，Twig_Function_Node的弃用
