Your specification is not too clear, and the code doesn't help understanding nor interpreting .
It is always beneficial to show WHAT exactly "doesn't work well". A few comments that jump to mind looking at your code :
- where is $7 used for computations?
- milkmonth and milkday will not have correct values as the substr parameters are wrong and could be moving.
- lastmilk is undefined for the first line, and not reset if $5 changes. This may be intended behaviour, though.
- endmilk is never used; why not drop it entirely?
- as startmilkdiff is the only variable in the printf stament, three %f format specifiers are redundant.
- as correspondent $5 values are NOT in sequence, you'd better work with arrays, or do a sort beforehand.

EDIT:
- plus, the mktime function requires 6 or 7 parameters; you supply 4 only.
- you want to output the difference in days, but calculate and print second values only.

px_date2string - Converts a date into a string.

SYNOPSIS
string px_date2string (resource $pxdoc, int $value, string $format) DESCRIPTION
Turns a date as it stored in the paradox file into human readable format. Paradox dates are the number of days since 1.1.0000. This func- tion is just for convenience. It can be easily replaced by some math and the calendar functions as demonstrated in the example below. PARAMETERS
o $pxdoc - Resource identifier of the paradox database as returned by px_new(3). o $value - Value as stored in paradox database field of type PX_FIELD_DATE. o $format - String format similar to the format used by date(3). The placeholders support by this function is a subset of those supported by date(3) (Y, y, m, n, d, j, L). RETURN VALUES
Returns TRUE on success or FALSE on failure. EXAMPLES
Example #1 Turn a paradox date into a human readable form <?php $px = px_new(); /* make up a date as it could be stored in */ /* a date field of a paradox db. */ /* 700000 days since 1.1.0000. */ $days = 700000; /* Use the calendar functions to print a */ /* human readable format of the date */ echo jdtogregorian($days+1721425)." "; /* px_date2string() outputs the same */ echo px_date2string($px, $days, "n/d/Y")." "; px_delete($px); ?> The above example will output: 7/15/1917 7/15/1917 SEE ALSO
