Framework: The `snake_case()` helper function doesn't work with dash case strings

Created on 5 Aug 2016 · 3Comments · Source: laravel/framework

I want to convert a dash case string (my-test-string) to snake case (my_test_string) with the snake_case() helper function but it doesn't work.

The problem is that the Str:snake() function doesn't look for dashes.

This regular expression would fix that:
/(.)(?=[A-Z]|-)/u

For anyone who arrived here from search, you can convert dash case (kebab case) to camel case, then from camel case to snake case (underscore case). Tested with Laravel 5.4.

$out = snake_case( camel_case( "my-test-string" ) )

The snake case function only converts from camel case to snake case.

@IllyaMoskvin it would if its all string. if there is numbers, it won't work, ex: sample-2, it will only convert to camel_case which is sample2.
