[PHP] Adding Dates (To Obtain Future Dates)

2001-11-13 Thread Robert Miller 

This problem took a while to figure out. I'm posting the solution so that =
other's may find this example. If you know of a better way, please reply. =
:-)

Cheers,

Rob

Problem: Generate Future Dates:
Sub-Problem: Future Dates are Dictated by Record Type (Permanent or =
Temporary)
The Script:

$cyear =3D date(Y);
$cmonth =3D  date(m);
$cday =3D date(d);
if ($sType =3D=3D p)
{
   $fyear =3D $cyear + 6
   $sExpiry =3D $fyear.$cmonth.$cday;
}
else
{
   $adv =3D $cmonth + 6;
   $newunix =3D mktime(0,0,0,$adv,$cmonth,$cyear);
   $sExpiry =3D date(Ymd, $newunix);
}

$sCreated =3D date(Ymd);
$sUpdated =3D date(Ymd);



It seems weird to have use months possibly greater than 12 ($adv =3D =
$cmonth + 6;), but hey... it works.

It is documented for mktime - it says '...it will automatically calculate 
the correct value for out of rnage input' and the examples include one 
where the month value is 13 (at least in my older docs).
