I want to use php functions like str_word_count with volt. For example, Split the output of {{ posts.post_con['post_category'] }}, It will something like
category1 category2 category3
and create links something like
<a href="cat/category1">category1</a><br />
<a href="cat/category2">category2</a><br />
<a href="cat/category3">category3</a><br />Create a Component, register it in the bootstrap, and call it in the volt template like {{ myComponent.myFunction("myParam") }}. In the function, you will return a string that contains that HTML code (beware of autoescape, it will affect the returned string).
At least this is what I remember.
You can extend Volt ; see https://docs.phalcon.io/en/latest/reference/volt.html#extending-volt
Or, if you want a quick & dirty solution: simply use PHP in your volt template with php open/close tags ; <?php $foo = "bar"; ?> will allow you to use {{ foo }} as a volt variable.
