note 98120 added to function.date-diff

This is a very simple function to calculate the difference between two datetime values, returning the result in seconds. To convert to minutes, just divide the result by 60. In hours, by 3600 and so on. Enjoy. <?php function time_diff($dt1,$dt2){ $y1 = substr($dt1,0,4); $m1 = substr($dt1,5,2); $d1 = substr($dt1,8,2); $h1 = substr($dt1,11,2); $i1 = substr($dt1,14,2); $s1 = substr($dt1,17,2); $y2 = substr($dt2,0,4); $m2 = substr($dt2,5,2); $d2 = substr($dt2,8,2); $h2 = substr($dt2,11,2); $i2 = substr($dt2,14,2); $s2 = substr($dt2,17,2); $r1=date('U',mktime($h1,$i1,$s1,$m1,$d1,$y1)); $r2=date('U',mktime($h2,$i2,$s2,$m2,$d2,$y2)); return ($r1-$r2); } ?> ---- Server IP: 187.16.23.134 Probable Submitter: 200.138.243.82 ---- Manual Page -- http://www.php.net/manual/en/function.date-diff.php Edit -- https://master.php.net/note/edit/98120 Del: integrated -- https://master.php.net/note/delete/98120/integrated Del: useless -- https://master.php.net/note/delete/98120/useless Del: bad code -- https://master.php.net/note/delete/98120/bad+code Del: spam -- https://master.php.net/note/delete/98120/spam Del: non-english -- https://master.php.net/note/delete/98120/non-english Del: in docs -- https://master.php.net/note/delete/98120/in+docs Del: other reasons-- https://master.php.net/note/delete/98120 Reject -- https://master.php.net/note/reject/98120 Search -- https://master.php.net/manage/user-notes.php
