php - Pulling in data around/after midnight -

ok.. i've created myself messy problem.

so have jquery slider shows 5 slides of content

1) -2 hours ago

2) -1 hour ago

3) (0) present

4) +1 hours

5) +2 hours

the content each slide decided time of day is. when comes trying go back/forwards 1 2 hours during run midnight , after midnight whole script breaks, , kills site.

<?php   $h = date('g', strtotime ("-2 hour")); //set variable $h hour of day. $m = date('i', strtotime ("-2 hour")); //set variable $m min of hour. $d = date('w', strtotime ("-2 hour")); //set variable $d day of week.  // saturday schedule if ($d == 6 && $h >= 0 && $h < 07) $file ='earlyhours.php'; else if ($d == 6 && $h >= 07 && $h < 09) $file ='breakfast.php'; else if ($d == 6 && $h >= 09 && $h < 12) $file ='throughthemorning.php'; else if ($d == 6 && $h >= 12 && $h < 13) $file ='rewind.php'; else if ($d == 6 && $h >= 13 && $h < 17 && $m <= 30) $file ='nonstop.php'; else if ($d == 6 && $h >= 17 && $m >= 30 && $h <21) $file ='livetrend.php'; else if ($d == 6 && $h >= 17 && $m >= 35 && $h < 21) $file ='nonstop.php'; else if ($d == 6 && $h >= 21 && $h < 18) $file ='gennation.php'; else if ($d == 6 && $h >= 23) $file ='earlyhours.php'; else if ($d == 7 && $h >= 0) $file ='earlyhours.php';  require $_server['document_root'] . '/collection/profiles/' . $file . '';  ?> 

as can see figures time , drops correct file in - there's 5 of these everyday of week (-2.php, -1.php, 0.php, 1.php, 2.php).

does have solution? ideally need stop break, don't want visitors scrolling +1 / 2 or -1 / 2 hours on same days rotation when nears, , steps on midnight.

for example, right code broken on -2.php until @ least 2am (my timezone) track.

i've totally burnt myself out trying figure 1 out.

the problems arising change of day can become intractable. i'd tackle different way. start calculating day , hour 5 periods interested in , use datetime heavy lifting. then, use function provide schedule item particular day/time combination.

here's skeleton

<?php date_default_timezone_set('pacific/auckland'); $now = new datetime(); $onehour = new dateinterval('pt1h'); $minusone =  (clone $now); $minusone->sub($onehour); $minustwo =  (clone $minusone); $minustwo->sub($onehour); $plusone =   (clone $now); $plusone->add($onehour); $plustwo =   (clone $plusone); $plustwo->add($onehour);  echo returnfile($minustwo); echo returnfile($minusone); echo returnfile($now); echo returnfile($plusone); echo returnfile($plustwo);  function returnfile(datetime $t) {     $day = $t->format('d');     $hour = $t->format('g');     // echo "day:$day, hour: $hour;<br>";     switch ($day) {         case 'mon':             if ($hour<7) {                 // small hours monday...                 $filename = "smallmonday.html";                 break;             }             if ($hour<12) {                // monday morning                 $filename = "morningmonday.html";                 break;             }             break;         case 'tue':             if ($hour >=23) {                 // late tuesday                 $filename = "latetuesday.html";             }         default:             $filename = "some other time";      }     return $filename; }  ?> 

i haven't put in complete schedule - can work out.

if you're using php 5.5 or later can use datetimeimmutable instead of datetime away cloning.

there's fiddle here
