New in version 1.5: The random function was added in Twig 1.5.
New in version 1.6: String and integer handling was added in Twig 1.6.

{{ random(['apple', 'orange', 'citrus']) }} {# example output: orange #}
{{ random('ABC') }} {# example output: C #}
{{ random() }} {# example output: 15386094 (works as the native PHP mt_rand function) #}
{{ random(5) }} {# example output: 3 #}
