aeroswat Posted December 8, 2009 Share Posted December 8, 2009 Is this the easiest way to filter a string to make it display only numbers? If so what would I use in this function?

aeroswat Posted December 8, 2009 Author Share Posted December 8, 2009 Would it be this? preg_replace(“/[^0-9]/”, “”, $string); Link to comment https://forums.phpfreaks.com/topic/184429-preg_replace/#findComment-973568 Share on other sites More sharing options...
cags Posted December 8, 2009 Share Posted December 8, 2009 If the objective is to replace everything in a string that is not a number with nothing, then that pattern will work (though the intelligent quotes or whatever they are called will like cause problems).
