note 90338 added to function.time

<?php // In reply to jon at freilich dot com // Some Fire Departments have 3 shifts // Each shift works for 24 hours, and works 5, 24 hour shifts berfore their break. // I was asked to provide the function so that their online calendar would output // What shift was on duty from Jan 2001 until, well forever. // this function is for wierd rotating schedules that have a set pattern, like Fire Departments // You need to provide the attributes for this function to work // $day = what day of the month, for example 9 // $date = use time() to check today or convert the date you want to check into seconds by using the function mktime(7,0,0,1,1,2009); function whatShift($day, $date) { $month = date("m", $date); // create the month by converting the attribute $date and getting what month you want. $year = date("Y", $date); // create the year by converting the attribute $date and getting what you you want. $date_in_question = mktime(7,0,0,$month, $day, $year); // HINT you need to use ROUND, otherwise, you will spend LOTS of time wondering why it does not work right! // What happens here is that we are doing the math and using modulus to find out what shift is on duty. // If the answer is 0, then that shift is on duty. // If you do not know what Modulus is, it gives you the remainder after something is divided by another // We use 15 because there is always 15 days between the first day of the set for each shift // and the start of the next set // A shift $ashift1 = (round(($date_in_question - mktime(7,0,0,1,8,2001)) / 86400) % 15); $ashift2 = (round(($date_in_question - mktime(7,0,0,1,10,2001)) / 86400) % 15); $ashift3 = (round(($date_in_question - mktime(7,0,0,1,12,2001)) / 86400) % 15); $ashift4 = (round(($date_in_question - mktime(7,0,0,1,14,2001)) / 86400) % 15); $ashift5 = (round(($date_in_question - mktime(7,0,0,1,16,2001)) / 86400) % 15); // B shift $bshift1 = (round(($date_in_question - mktime(7,0,0,1,13,2001)) / 86400) % 15); $bshift2 = (round(($date_in_question - mktime(7,0,0,1,15,2001)) / 86400) % 15); $bshift3 = (round(($date_in_question - mktime(7,0,0,1,17,2001)) / 86400) % 15); $bshift4 = (round(($date_in_question - mktime(7,0,0,1,19,2001)) / 86400) % 15); $bshift5 = (round(($date_in_question - mktime(7,0,0,1,21,2001)) / 86400) % 15); // C shift $cshift1 = (round(($date_in_question - mktime(7,0,0,1,3,2001)) / 86400) % 15); $cshift2 = (round(($date_in_question - mktime(7,0,0,1,5,2001)) / 86400) % 15); $cshift3 = (round(($date_in_question - mktime(7,0,0,1,7,2001)) / 86400) % 15); $cshift4 = (round(($date_in_question - mktime(7,0,0,1,9,2001)) / 86400) % 15); $cshift5 = (round(($date_in_question - mktime(7,0,0,1,11,2001)) / 86400) % 15); // A shift // If any one of these equals 0, then A shift is on duty. if (($ashift1 == 0) || ($ashift2 == 0) || ($ashift3 == 0) || ($ashift4 == 0) || ($ashift5 == 0)) { $message = '<div style="background-color: #060; color: #FFF; text-align: center;">'.$day.' is an A shift day</div>'; } // B shift // If any one of these equals 0, then B shift is on duty. if (($bshift1 == 0) || ($bshift2 == 0) || ($bshift3 == 0) || ($bshift4 == 0) || ($bshift5 == 0)) { $message = '<div style="background-color: #060; color: #FFF; text-align: center;">'.$day.' is a B shift day</div>'; } // C shift // If if any one of these equals 0, then C shift is on duty. if (($cshift1 == 0) || ($cshift2 == 0) || ($cshift3 == 0) || ($cshift4 == 0) || ($cshift5 == 0)) { $message = '<div style="background-color: #060; color: #FFF; text-align: center;">'.$day.' is a C shift day</div>'; } // This is just in case something wierd happens if (empty($message)) { $message = "ERROR!"; } return $message; } ?> ---- Server IP: 209.41.74.194 Probable Submitter: 68.13.171.69 ---- Manual Page -- http://www.php.net/manual/en/function.time.php Edit -- https://master.php.net/note/edit/90338 Del: integrated -- https://master.php.net/note/delete/90338/integrated Del: useless -- https://master.php.net/note/delete/90338/useless Del: bad code -- https://master.php.net/note/delete/90338/bad+code Del: spam -- https://master.php.net/note/delete/90338/spam Del: non-english -- https://master.php.net/note/delete/90338/non-english Del: in docs -- https://master.php.net/note/delete/90338/in+docs Del: other reasons-- https://master.php.net/note/delete/90338 Reject -- https://master.php.net/note/reject/90338 Search -- https://master.php.net/manage/user-notes.php
