Tip: mySQL for example, has very good date-routines. It eats nearly every kind of date correctly. So if you use a DB, it is not so a bad idea to use the routines from it, cause the routines in the DB also can correct the year. This trick can ship you around problems with Y2K. You can do for example: $formdate="28.01.99"; # comes normally from your input form, her e.g. german date # This lines splits it up: one or more digits, seperated by non-digits $mydate=ereg("([[:digit:]]+)[^[:digit:]]([[:digit:]]+)[^[:digit:]]([[:digit:]]{2,4})",$fromdate,$regs); $newdate="$regs[3]-$regs[2]-$regs[1]"; # date is now "99-01-28" $r=mysql("BLA_DB","SELECT UNIX_TIMESTAMP('$newdate') as d"); if ($d=mysql_result($r,0,"d")>0) { # Date is correct echo Date("d.m.Y",$d); # will show now 28.01.1999 # remark, that mySQL assumes, that years < 70 or so are in year 2000 and up }
