php if else statement time schedule - php

Question

I'm using PHP to schedule images to come up on a website at a specific time. I'm fine until a picture has to come up say at 9:42am and end at 10:42am. a can get top of hours and partial hours ending at top of hour but I can't figure out how to schedule multiple partial hours in a row. This is what I'm using
date_default_timezone_set('America/Los_Angeles');
$h = date('G');
$m = date('i');
$d = date('w');
$year = date('Y');
// MONDAY SCHEDULE
if ($d == 1 && $h >= 0 && $h < 1) { $img = 'opendoor.jpg'; }
else if ($d == 1 && $h >= 13 && $h < 14) { $img = 'newtime.jpg'; }
else if ($d == 1 && $h >= 14 && $h < 15) { $img = 'weekend'; }
else if ($d == 1 && $h >= 15 && $h < 16) { $img = 'today.jpg'; }
else if ($d == 1 && $h >= 16 && $h <= 17 && $m >= 0 && $m < 30) { $img = 'walk.jpg'; }
else if ($d == 1 && $h >= 17 && $h < 19 && $m > 30) { $img = 'new.jpg'; }
else if ($d == 1 && $h >= 19 && $h < 20 && $m < 30) { $img = 'default.jpg'; }
else if ($d == 1 && $h >= 19 && $h < 20 && $m > 30) { $img = 'test.jpg'; }
I followed a very good example given to me for my question, but for no apparent reason, some of the hours work and some doesn't. When I echo $img on one hour the code is printed but on the hour before or after it is ommitted. Here is a partial code of what I'm now doing:
date_default_timezone_set('America/Los_Angeles');
$h = date('G');
$m = date('i');
$d = date('w');
$hhmm = date('H') * 100 + date("i");
$img = key(array_filter(array(
'images/hosts/image1.jpg' => ($d == 0 && $h >= 0 && $h < 1),
'images/hosts/image2.jpg' => ($d == 0 && $hhmm >= 0100 && $hhmm <= 0542 ),
'images/hosts/image3.jpg' => ($d == 0 && $hhmm >= 0542 && $hhmm <= 0600),
'images/hosts/image4' => ($d == 0 && $hhmm >= 0600 && $hhmm < 0630),
'images/hosts/image5' => ($d == 0 && $hhmm >= 0630 && $hhmm < 0800),
'images/hosts/image5.jpg' => ($d == 6 && $h >= 8 && $h < 9)

Answer 1

If you want to compare "partial hours", then it might be best to combine hours and minutes into one value. You can often get away with hours*100+minutes:
$h = date('G');
$m = date('i');
$d = date('w');
$hhmm = data("H") * 100 + date("i");
So $hhmm would be 1230 for 12:30am, or 1942 for 7:42pm. The numbers jump between 1759 and 1800, but that's not an issue since you only want to compare with <= and => within time ranges anyway.
Also I would totally rewrite the if/else chain into an array comparison:
$img = key(array_filter(array(
'opendoor.jpg' => ($d == 1 && $h >= 0 && $h < 1),
'newtime.jpg' => ($d == 1 && $h >= 13 && $h < 14),
...
'partialhours.jpg' => ($hhmm => 2142 && $hhmm <= 2242),
)));

Answer 2

please use switch
switch ($d)
{
case 1:
switch ($h)
{
case 1: $img = 'opendoor.jpg'; break;
case 13: $img = 'newtime.jpg'; break;
case 14: $img = 'weekend.jpg'; break;
case 15: $img = 'today.jpg'; break;
case 16:
if ($m<30) $img = 'walk.jpg';
break;
case 17:
$img = ($m>30) ? 'new.jpg':'walk.jpg';
break;
case 18:
if ($m>30) $img = 'new.jpg';
break;
case 19:
$img = ($m>30) ? 'test.jpg':'default.jpg';
break;
}
break;
}
