Update regex to avoid /e depreciation

[felipeumpierre]

Update the regex line to avoid the notice message:

The /e modifier is deprecated, use preg_replace_callback

php version: 5.6.13

Thanks for checking, yes, it seems, that's gonna be not supported soon, but the solution is not what is pulled, It need to be changed to preg_replace_callback(). I will fix it as soon as possible.

I updated my commit changing the pre_replace to preg_replace_callback.
