As you may know, there are more than just one RegEx flavour: PCRE, one from Java, one from .NET ... etc, and all of them have a little different syntaxes and some have a feature more or less.
Now my question is, if somebody knows if it is possible to use, for example, the flavour from .NET in PHP.
I need this respectively I wonder if this is possible because I want to make a little Regular Expression checker for my website and there I want to give the user the choice you select his flavour...
Or is the only one solution to convert the patterns from one flavour to another manually?
