I am trying to use php function transliterator_transliterate but get an error when I call it

Trying to use this function in php7 and in Laravel framework

transliterator_transliterate('Any-Latin; Latin-ASCII; [\u0080-\uffff] remove', $str);

Call to undefined function App\Http\Controllers\Backend\Core\Blog\transliterator_transliterate()

http://php.net/manual/en/transliterator.transliterate.php

It's supposed to be available on (PHP >= 5.4.0, PECL intl >= 2.0.0)

Do I need some extension for this function?
