note 69502 deleted from function.strtotime by derick

Note Submitter: drew at drew dot plznospam dot co dot il ---- In my current project, I had the need for strtotime to calculate dates in the near past and future, only to use business days (i.e. skip weekends) so I wrote a wrapper function that will use strtotime but if the resulting date is a weekend or holiday it will keep going back or forward. Basically I needed "strtotime('-2 days')" to go back to Friday if I called it on a Tuesday (since 2 days ago was Sunday). This makes use of the getHolidays function written by codepanda at yahoo dot com and submitted on 24-Aug-2005, so special thanks for that. I am unable to include it w/out the site complaining my message is too long. <?php /** * Converts a string to timestamp, skipping weekends and holidays if applicable * For example if today is Tuesday, strtotime_bizdays('-2 days'); returns the previous Friday since it first lands on Sunday * The function will check for holidays and recurse on itself if skipping weekends lands on a holiday, or vice versa. * * @author "Drew Phillips" <drew at drew dot co dot il> * @param string $str The date string to convert * @param int $now The timestamp representing the current time * @return int The timestamp of the calculated date */ function strtotime_bizdays($str, $now = null) { static $holidays = array(); //keep it around to speed up more than 1 call if ($now == null) $now = time(); $year = date('Y', $now); if (!array_key_exists($year, $holidays)) //dont have the holidays for this year yet, get em $holidays[$year] = getHolidays($year); $time = strtotime($str, $now); if ($time < $now) //looks like the $str references the past $sign = '-'; else //future $sign = '+'; if ( (date('w', $time) == 0 && $sign == '+') || (date('w', $time) == 6 && $sign == '-') ) //Sun going forward || Sat going back $time = strtotime("+1 day", $time); else if ( date('w', $time) == 0 && $sign == '-' ) //Sun going back $time = strtotime("-2 days", $time); else if ( date('w', $time) == 6 && $sign == '+' ) //Sat going forward $time = strtotime("+2 day", $time); $key = date('Y-m-d', $time); //array key for holiday $year = date('Y', $time); //year for checking if we changed years if (!array_key_exists($year, $holidays)) //moved into another year $holidays[$year] = getHolidays($year); if (array_key_exists($key, $holidays[$year])) { //we're on a holiday if ($sign == '+') { $time += 86400; } else { $time -= 86400; } $time = strtotime_bizdays( date('Y-m-d H:i:s', $time) ); //check in case moving off the holiday hit a weekend } return $time; } ?>
