[RESOLVED] [REGEX] from 01 to 31

whisher06

Hi.
I've got a lot of troubles to validate
a string from 01 to 31.
I've made this simple pattern but

$isValid=(bool)preg_match('/[0-3]{1}[0-9]{1}/','01');//true
var_dump($isValid);
echo " ";
$isValid2=(bool)preg_match('/[0-3]{1}[0-9]{1}/','07');//true
var_dump($isValid2);
echo " ";
$isValid3=(bool)preg_match('/[0-3]{1}[0-9]{1}/','08');//true
var_dump($isValid3);
echo " ";
$isValid4=(bool)preg_match('/[0-3]{1}[0-9]{1}/','31');//true
var_dump($isValid4);
echo " ";
$isValid4=(bool)preg_match('/[0-3]{1}[0-9]{1}/','20');//true
var_dump($isValid4);
echo " ";
$isValid5=(bool)preg_match('/[0-3]{1}[0-9]{1}/','32');//true
var_dump($isValid5);
echo " ";

Best wishes.

Sorry, I made a mistake 😉
it's impossible to check a query
string with a date like this

?d=07&m=09&y=2007

with the regex only ie 29/02 .
The job needs more work 😉

if(checkdate($_GET['m'], $_GET['d'], $_GET['y']))
{
   $date = sprintf('%04d-%02d-%02d', $_GET['y'], $_GET['m'], $_GET['d']);
}
else
{
   // invalid date
}

Thanks a lot for the sprintf syntax I always used
sprintf with %d and %s only :o
Now I can use date_format without any hassle
with

$date = sprintf('%04d%02d%02d', '2002', '2', '28');

AND I didn't know checkdate
I'm very pleased tonight 😃

Thanks a lot again.

Bye.
