Use PHP functions in TWIG templates

ravenflux/php-functions is TWIG extension that implements a way to use native PHP functions and filters in TWIG template.

Function VS Filter

source

A function is used when you need to compute things to render the result.
A filter is a way to transform the displayed data.

Usage

{{ count(users) }}
{{ user.name|nl2br }}

or dynamically any php function:

{{ raven_function('count', users) }}
{{ user.name|raven_filter('nl2br') }}

Installation

The recommended way to install is via Composer:

composer require ravenflux/php-functions

For Symfony usage add it as a service and tag it:

# config/services.yaml
parameters:
    ravenflux_functions:
        - 'count'
    ravenflux_filters:
        - 'nl2br'

services:
    ravenflux.twig.extension.php_functions:
        class: RavenFlux\Twig\PhpFunctionsExtension
        arguments:
            - '%ravenflux_functions%'
            - '%ravenflux_filters%'
        tags:
            -
                name: twig.extension

or inline without extra parameters:

# config/services.yaml
services:
    ravenflux.twig.extension.php_functions:
        class: RavenFlux\Twig\PhpFunctionsExtension
        arguments:
            - #first argument are functions
                - 'count'
            - #second argument are filters
                - 'nl2br'
        tags:
            -
                name: twig.extension

or without any arguments if you want to use dynamic function / filters:

# config/services.yaml
services:
    ravenflux.twig.extension.php_functions:
        class: RavenFlux\Twig\PhpFunctionsExtension
        tags:
            -
                name: twig.extension
