Date Range Validation

kayners

Hello,

I'm a sysadmin who just took over a php application and have no php training. I have this function:

function verify_uspap_completion_date($d)
{
@list($mm,$dd,$yyyy) = @explode("/",$d,3);

if(!@checkdate($mm,$dd,$yyyy)) return false;

if($yyyy < date("Y")-2 || $yyyy > intval(date("Y"))) return false;

return true;

}

I need to change the rule (line 4 if you don't count brackets)

if($yyyy < date("Y")-2 || $yyyy > intval(date("Y"))) return false;

...to a "number of days" calc where it's false when the date is greater than two years ago. The version above would seem to allow dates back to 1/1/2005, when I need to limit it to 10/16/2005 (as of today).

BTW, this is version 4.x on a Mac server.

TIA,
Steve.

I did a little reading there, although I got lost fairly quickly. Looks like a string conversion function. Can it convert a date to a number?

I'm looking for a date range validation based on from (today) to (today-2yrs)

[man]strtotime[/man]
The function expects to be given a string ... and will try to parse that format into a ... number of seconds ....

It can, for example, parse strings like "now", and "2 years ago" and return numbers like 1195422060 and 1132350074.

An alternative is to write a comparison function that looks at month and day as well as year, and then use that in the if() test.
