note 110970 added to function.date-diff

Hi There, is still confused on the php changes. My script worked fine until the release of php 5.3. I tried many things but i always got this error: Warning: date_diff() expects parameter 1 to be DateTime, string given in / the code: if (! function_exists(date_diff)) { function date_diff($start_date, $end_date, $returntype="d") { if ($returntype == "s") $calc = 1; if ($returntype == "m") $calc = 60; if ($returntype == "h") $calc = (60*60); if ($returntype == "d") $calc = (60*60*24); $_d1 = explode("-", $start_date); $y1 = $_d1[0]; $m1 = $_d1[1]; $d1 = $_d1[2]; $_d2 = explode("-", $end_date); $y2 = $_d2[0]; $m2 = $_d2[1]; $d2 = $_d2[2]; if (($y1 < 1970 || $y1 > 2037) || ($y2 < 1970 || $y2 > 2037)) { return 0; } else { $today_stamp = mktime(0,0,0,$m1,$d1,$y1); $end_date_stamp = mktime(0,0,0,$m2,$d2,$y2); $difference = round(($end_date_stamp-$today_stamp)/$calc); return $difference; } I hope someone have a idea? ---- Server IP: 69.147.83.199 Probable Submitter: 84.170.136.140 ---- Manual Page -- http://php.net/manual/en/function.date-diff.php Edit -- https://master.php.net/note/edit/110970 Del: integrated -- https://master.php.net/note/delete/110970/integrated Del: useless -- https://master.php.net/note/delete/110970/useless Del: bad code -- https://master.php.net/note/delete/110970/bad+code Del: spam -- https://master.php.net/note/delete/110970/spam Del: non-english -- https://master.php.net/note/delete/110970/non-english Del: in docs -- https://master.php.net/note/delete/110970/in+docs Del: other reasons-- https://master.php.net/note/delete/110970 Reject -- https://master.php.net/note/reject/110970 Search -- https://master.php.net/manage/user-notes.php
