The function won`t work for Years smaller than 33. If you enter `16.09.00` the function returns nothing.
That`s because in the check for `d.m.y`, `16.09.00` returns $p3=0 and the clause is $p3>32.
Change the function as below, substituting `>32` with `>=0` and it will work perfectly!
// check `d.m.y`
if (($p1>0 && $p1<32) &&
($p2>0 && $p2<13) &&
($p3>=00)) //change this one
{
$y=$p3;
$m=$p2;
$d=$p1;
}
// check `y.m.d`
if ($y == "" &&
($p1>=00) && //and this one
($p2>0 && $p2<13) &&
($p3>0 && $p3<32))
{
$y=$p1;
$m=$p2;
$d=$p3;
}
