note 112472 added to datetime.diff

After wrestling with datetime diff for a while it finally dawned on me the problem was both in the formatting of the input string and the formatting of the output. The task was to calculate the duration between two date/times. ### Calculating Duration 1. Make sure you have a valid date variable. Both of these strings are valid: * 2013-06-19 18:25 * 06/19/13 18:25 2. Next convert the string to a date variable ~~~ $dteStart = new DateTime($strStart); $dteEnd = new DateTime($strEnd); ~~~ 3. Calculate the difference ~~~ $dteDiff = $dteStart->diff($dteEnd); ~~~ 4. Format the output ~~~ # you cannot combine the output thus the following line does not work. print($dteDiff->format("H:I:S")); # DOES NOT WORK # Instead, you have to return each level of the interval print($dteDiff->format("%H").':'); print($dteDiff->format("%I").':'); print($dteDiff->format("%S")); ~~~ ---- Server IP: 69.147.83.199 Probable Submitter: 69.105.136.77 ---- Manual Page -- http://php.net/manual/en/datetime.diff.php Edit -- https://master.php.net/note/edit/112472 Del: integrated -- https://master.php.net/note/delete/112472/integrated Del: useless -- https://master.php.net/note/delete/112472/useless Del: bad code -- https://master.php.net/note/delete/112472/bad+code Del: spam -- https://master.php.net/note/delete/112472/spam Del: non-english -- https://master.php.net/note/delete/112472/non-english Del: in docs -- https://master.php.net/note/delete/112472/in+docs Del: other reasons-- https://master.php.net/note/delete/112472 Reject -- https://master.php.net/note/reject/112472 Search -- https://master.php.net/manage/user-notes.php
