date - Error (?) in Day counting PHP -



date - Error (?) in Day counting PHP -

<?php $date1 = "2002-1-1"; $date2 = "2021-12-31"; $deff = abs(strtotime($date2) - strtotime($date1)); $daycount = $deff / (60 * 60 * 24); echo $daycount; ?>

why reply 7304 instead of 7300 trying calculate number of days 20 years?

please help.

use datetime this:

$datetime1 = new datetime("2002-1-1"); $datetime2 = new datetime("2021-12-31"); $interval = $datetime1->diff($datetime2); $elapsed = $interval->format('%a days'); echo $elapsed;

see in action

reference

datetime dateinterval

php date datetime date-math

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
