datetime - How to fix date inconsistency from external source PHP -


i have issue. dates api come me feb 4 2016. have apply date modifications need date in format 02-04-2016. code works dates returned api above 9, such feb 10 2016 because when manipulate this, neatly 02-10-2016. however, problem dates below 10, such feb 4 2016 because these lead 02-4-2016 causes error.

what know how can consistently format of 02-04-2016 regardless of dates api above 9 or below 10. following code.

// split checkin  date string api list($month, $day, $year, $time) = explode(' ', $checkindate);   // change short month name (e.g feb) month number (e.g. 02) $monthname = $month; $month = date('m', strtotime($monthname));  // new checkin date in example format 02-20-2016  $checkin_new = $month.'/'.$day.'/'.$year; // part causes error when date returned api below 10, example feb 4 2016. other dates above 9 such feb 10 2016 work , don't cause issue.   // subtract days  $newdate = new datetime($checkin_new );   $subtracteddate = $newdate->modify("-1 day");

for getting date in february use mktime function:

echo date("m d y ", mktime( 0,0,0,2, 4, 2016)); echo "<br />"; echo gmdate("m d y ", mktime( 0,0,0,2, 2, 2016));

this give output:

feb 04 2016 feb 01 2016

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
