linux c/c++ preg_replace type of function?

Question

I'm trying to figure out an preg_replace() (php) style function that I can use in c++ (linux).

Can someone help me translate this?

$str = preg_replace(array('/\s+/','/[^A-Za-z0-9\-]/'),array('-',''),$str);

Answer 1

Best option would be to link with the Perl Compatible Regular Expression (PCRE) library and use the functions it provides.

You can check pcrecpp(3) for more info. A sample code would be:

#include <pcrecpp.h>

pcrecpp::RE("\s+").Replace("-", &s); // where s is the target string
pcrecpp::RE("[^A-Za-z0-9\-]").Replace("", &s);

Answer 2

You can use the boost::regex library
