Concatenate multiple twig variables in one bracket

Question

I want to concatenate 3 variables in one bracket, like PHP.

i.e

In PHP:

getimagesize($path.$image)

We can concatenate variables with dot notation. How can I reproduce this in twig?

{{ path.key }} isn't working as intended.

Answer 1

Use the tilde character ~ to concatenate string and/or variables.

~: Converts all operands into strings and concatenates them. {{ "Hello " ~ name ~ "!" }} would return (assuming name is 'John') Hello John!.

Read about it in the documentation.
