str()

Functions prefixed with str_ perform tasks that are useful when dealing with strings. The helper maps directly to the Str PHP class and its methods. For example:

{{ str_camel() }}

The above is the PHP equivalent of the following:

<?= Str::camel() ?>

Methods in camelCase should be converted to snake_case.

You may also apply the string functions as a Twig filter.

{{ ''|str_camel }}

str_limit()

str_words()

Limit the number of words in a string.

{{ str_words('The quick brown fox...', 100) }}

To add a suffix when limit is applied, pass it as the third argument. Defaults to ....
