Question about DATE function

badgoat

Hello!

How would I go about computing the time, every 45 minutes after a user-entered time? for example, a user enters 05:00, I would like to see
05:45
06:30
07:15
08:00

etc

I figure it will be done using DATE, so I have tried:

$s1 = $sunuptime(date('G:i')+0:45);
<tr>
    <td>1st</td>
    <td>' .$s1. '</td>
</tr>

But I am getting an error, pointing to a problem with my $s1= line.. I am unsure how to format it so it would add 45 mins to the time entered.

(Looking at the code, I am certain I am royally screwing it up, I am, now wondering if I need to convert the time entered to a DATE

$s1=date('G:i')

And then figure a way to add 45 mins to that...

hm.. interesting problem..

You could use the [man]mktime/man function I suppose.
But let me play unfair:

[man]date_sunrise[/man]

(PHP 5)

date_sunrise — Returns time of sunrise for a given day and location

<?php
$userTime = "05:00";
list($hr, $min) = explode(':', $userTime);
$dateTime = mktime($hr, $min);
printf("<table>\n<tr><td>%s</td>", date("H:i", $dateTime));
for($period = 1; $period <= 4; $period++)
{
   $dateTime = strtotime('+45 minutes', $dateTime);
   printf("<td>%s</td>", date("H:i", $dateTime));
}
echo "</tr>\n</table>\n";
?>

NogDog: Many thanks, after reading your code and seeing the results, I see relatively clearly what everything does, and it works well. Much appreciated!
