Twig Components / Methods / preg_grep

Note: You are currently reading the documentation for Bolt 5.0. Looking for the documentation for Bolt 5.2 instead?

preg_grep(pattern, flags = "") is a Twig filter to perform a regular expression match and return an array of entries that match the pattern.

{% set values = [..., ..., ...] %} 
{{ values|preg_grep("/^(\d+)?\.\d+$/");
