symfony - Twig: Unknown "localizednumber" filter -

-

when applying twig filter "localizednumber", following error thrown:

unknown "localizednumber" filter in mybundle:home:home.html.twig @ line 558.

i have installed twig extensions php intl.

what issue here?

did declare intl extension in services?

if not, add this:

<service id="twig.extension.intl"          class="twig_extensions_extension_intl">     <tag name="twig.extension" /> </service>

in app/config/services.xml.
