Since I can t comment on Jasper s answer  I d like to point out a small bug in his solution    str replace    a-z0-9 s  gi      replace     s  g   -      The problem is that first code removes all the hyphens and then tries to replace them     You should reverse the replace calls and also add hyphen to second replace regex  Like this   str replace     s  g   -   replace    a-z0-9- s  gi
