anyone got out to do this on php - uk date format as well
i first though id take DMY format and convert them to unix epoch but for some reason it turns 31st feb into a date in july
all things lifted off net examples have been far to ott or not worked
also a reg ex for ip`s that works would be good whilst im at it as iv had issue on that as well

Good place for regular expressions not sure about the php dates q though
http://regexlib.com/Default.aspx
Expression:
^(25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[1-9])\.(25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[1-9]|0)\.(25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[1-9]|0)\.(25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[0-9])$
Description: RegExp for validating the format of IP Addresses.
Matches: 127.0.0.1|||255.255.255.0|||192.168.0.1
Non-Matches: 1200.5.4.3|||abc.def.ghi.jkl|||255.foo.bar.1 _________________

This one looks ok : http://www.smartwebby.com/PHP/datevalidation.asp
I dont know php very well but with the example given I would do the overall check first, then do month then year, then validate the days so that you can test the days in the month correctly....
Sort of :
Code: $month=substr($strdate,($pos+1),($pos));
$date=substr($strdate,0,($pos));
$year=substr($strdate,($pos+4),strlen($strdate));
}
if((($month=09)OR($month=04)OR($month=06)OR($month=11))AND(($date<=0)OR($date>30))){echo "30 days hath september, April June and November, Enter a Valid Date";}
{

slaps why not populate the forms with list boxes and let people select dates?
That way if someone selects feb, you can tell the other box to only have 28 values in it. This stops the need for validation as you do it before they even enter it
Box1 Month
Box2 Day
etc

You tried this one?
http://www.vrooms.net/code.php?cat_select=PHP_Date_Validation&show=Date_Validation_and_Conversion
I expect you know all this, but I don't understand how you get the form data into variables on the php code.
Code: if ( $month==2 )
{
if ( $year % 4 != 0 )
$dpm[2] = 28;
else if ( $year % 400 == 0 )
$dpm[2] = 29;
else if ( $year % 100 == 0 )
$dpm[2] = 28;
else
$dpm[2] = 29;
}
I still don't understand how this works out whether it is a leap year. $dpm is the number of days in the month... I could do with sumat like this for a form I've got.. _________________

Regex is to make sure that theres no bug that will eventually corrupt the data, and make it worth all shite.
You do NOT wannahave the user type in like 31-2-2007 in a clear text. But as pointed out, youd wanna use drop-down boxes. _________________ Codito Ergo Sum | Even i, who have no clue about social life

Box1 Month
Box2 Day
thats the day its done soz forcey i didnt see that, but due to having to stick to uk date format i cant see how, other wise it would be easy with php / sessions and dynamically change the days in the form
chadk / slayer please stay out of this thread with your smarty arse comments that mean nothing
again a big thank you to everyone else in here who has tried to be constuctive _________________
