I have imagined this moment for a long time. Is it real? Could it be T-Regx got 60 stars ? :D

But, what's new?

There is preg_grep() function for filtering an array by a pattern, unfortunately there's no flag or another method to filter it by keys (there is a T-Regx method forArray()->filterByKeys(), but there was no such solution in SafeRegex).

That's why we added preg::grep_keys(), which works exactly like preg_grep() but filters an array by keys, instead of values. It's going to be released in 0.9.2.

List of all changes incoming in 0.9.2 is available in ChangeLog.md, with fluent(), unique(), in-place replacements and more.
