I'm translating (hacking) code from Perl to PHP and have two reg exp expressions I can't figure out what they do.
1st: $goodbadnum =~ tr/0-9//cd; I think this one removes any chars that are not numbers. 2nd: $goodbadnum =~ tr/0-9/x/; I think this one replaces and numbers with an 'x'. Right, wrong?? Robin E. Kopetzky Black Mesa Computers/Internet Services www.blackmesa-isp.net
