Duplicated PR #258.

And it seems that using the preg_match to accomplish the hasUppercase and hasLowercase methods.

[hasukmistry]

@peter279k I thought preg_match will be quick to perform the operation. Although I am open to suggestions here. If I can make my code better.

[peter279k]

Hi @hasukmistry, thanks for your reply.

It makes sense and I close PR #258.

Could you add more tests for these methods? And it can make their behaviors reliable :).

Such as adding the English uppercase/lowercase strings.

@hasmukhmistry13 thanks you so much for your time to contribute really appropriated

You're most welcome to contribute more...

[hasukmistry]

@peter279k @Lablnet I will try to add more tests for these methods. And create another PR afterward.
