Carbon::hasFormat("01/01/2019", 'd/m/Y'): preg_match(): Unknown modifier '('

[marktopper]

Hello,

I encountered an issue with the following code:

Carbon::hasFormat("01/01/2019", 'd/m/Y')

Carbon version: 2.24.0

PHP version: 7.2.22

I expected to get:

true

But I actually get:

PHP Warning:  preg_match(): Unknown modifier '(' in /var/www/application/vendor/nesbot/carbon/src/Carbon/Traits/Comparison.php on line 868

Thanks!
