Homework and Emergencies Homework & Coursework Questions help with the date difference Post 302502689 by DGPickett on Tuesday 8th of March 2011 03:41:37 PM

One technique I have used is to start time on March 1 of a leap year, so the future stretches out as 4 year sets, some with an extra day at the very end. When subtracting from a 4 year set the months in rotation, one never needs 29, as the most variable month is at the residue at the end after you subtract 47 months.

In UNIX, one usually just goes to UNIX time, subtracts, and then goes forward evaluating the residue, but if the app needs time in months, then it is more a question of the carry on subtract of dates, and of course the months, the leap year.

So, how close is your program -- what is a defect case?

MSQL_FETCH_OBJECT(3)													      MSQL_FETCH_OBJECT(3)

msql_fetch_object - Fetch row as object

SYNOPSIS
object msql_fetch_object (resource $result) DESCRIPTION
msql_fetch_object(3) is similar to msql_fetch_array(3), with one difference - an object is returned, instead of an array. Indirectly, that means that you can only access the data by the field names, and not by their offsets (numbers are illegal property names). Speed-wise, the function is identical to msql_fetch_array(3), and almost as quick as msql_fetch_row(3) (the difference is insignificant). PARAMETERS
o $ result -The result resource that is being evaluated. This result comes from a call to msql_query(3). RETURN VALUES
Returns an object with properties that correspond to the fetched row, or FALSE if there are no more rows. EXAMPLES
Example #1 msql_fetch_object(3) example <?php $con = msql_connect(); if (!$con) { die('Server connection problem: ' . msql_error()); } if (!msql_select_db('test', $con)) { die('Database connection problem: ' . msql_error()); } $result = msql_query('SELECT id, name FROM people', $con); if (!$result) { die('Query execution problem: ' . msql_error()); } while ($row = msql_fetch_object($result, MSQL_ASSOC)) { echo $row->id . ': ' . $row->name . " "; } msql_free_result($result); ?> CHANGELOG
