How to Concatenate/Combine Variables and Strings [Twig]

This article introduces how to combine variables and strings within a Twig template.

Although I've actually introduced this topic in the section on operators available in Twig, I'm writing it as a separate entry so I can easily recall it with a more descriptive title when I actually use it myself.

CONCATENATING VARIABLES AND STRINGS USING "~"

{% set name = 'tester' %}
{{ "Hello " ~ name ~ "!" }}
// result
Hello tester!

COMBINING VARIABLES AND STRINGS USING "#{expression}"

{{ "foo #{1 + 2} baz" }}
// result
foo 3 baz

It's used for calculations, such as expressions, but you can, of course, also use variables.

{% set name = 'tester' %}
{{ "foo #{name} baz" }}
// result
foo tester baz

It's like this. I feel that combining variables and strings is surprisingly common.

RECOMMENDED BOOKS FOR TWIG

I haven't read any books exclusively dedicated to Twig, but I found some on Amazon Kindle.
