time increment

sissy

Hi folks,

weekend is here hope you all have fun and go see Star Wars 🙂

function formatTime($myTime)
{
	preg_match('#(\\d{1,2})[:\\.](\\d{1,2})[\\s]*(am|pm)#i', $myTime, $matches);

$meridien = $matches[3];

$timestamp = strtotime(str_replace('.', ':', $myTime));

return date('YmdHis', $timestamp);
}

$test = array('2.25 am', '10:30 am', '12.10 pm', '8.00 pm', '10.30 pm', '12.30 am', '1.00 am', '3.30 am');

foreach ($test as $x)
{
	echo formatTime($x) . '<br>';
}

What i need to do is once it goes thru the am and pm times then it moves into the next day am times is increment by 24hrs.

i know to use 24 60 60 but i dont know how to track that it has reached midnight and going into the next day 🙁

appreciate your help folks, thanks.

You seem to be working way too hard here. What is it exactly that you're trying to accomplish? Chances are, PHP has a function that will do what you want without having to jump through all these hoops.

hi kburger,

i wish i was working too hard 🙂 then i would probably have an easier solution, however i dont see one.

i get my time format in the above test array().

i left the preg_match there cause i was trying to use the am/pm to work it out but theres probably an easier way.

here what the output produces.

the start of the time is always assumed today.

20050522022500 2.25am today
20050522103000 10.30am today
20050522120000 12.00pm today
20050522200000 8.00pm today
20050522223000 10.30pm today
20050522002000 0.20am new day should be 20050523002000
20050522010000 ...
20050522033000 3.30am new day should be 20050523033000

as you can see once we reach midnight and past we need to add 24hrs to it to send it into a new day.

Hope this makes it clearer.

many thanks.

I've read this, and re-read this. And I still can't quite figure out exactly what you're trying to do. What's the real world usage of your function? Surely it's not designed to be used to receive a random time and return some type of date string timestamp of sometimes today and sometimes tomorrow. If so, how could it ever be expected to know that a '2:25 am' passed to it is expected to be treated as 'today' and a '1:00 am' passed to it is expected to be treated as 'tomorrow'. A function has no knowledge of what it's been sent previously (unless you want to do some sort of external data storage within the function).

I'm just not getting what you're tyring to do. Maybe it's just me. Anybody else want to chime in? Maybe I'm missing something here.

If you take a look at http://www.ebroadcast.com.au/cgi-bin/TV/byChannel?date=Sunday_22_May&chan=10&state=Sydney&fta=1

you will see the times (tv guide) im talking about. Sure the times are sort of random but they ALWAYS start in todays morning and finish into tomorrows morning.

The timestamp is needed to write to an xml file for valid parsing.

So times in the above link are always very consistant just need to be able to add 24hrs to the ones that are midnight and beyond for that day.

After reading your PM, it looks like you might be able to make use of the 'static' declaration if I'm understanding your problem correctly. You can check out the documentation here .

Your function seems to need a way of knowing what it was passed previously. If it is currently being passed an 'am' time, and the last time it was used it was passed a 'pm' time, then you want to add the 24 hours to it. Am I understanding you correctly? The static declaration should allow you to do that if it's implemented right.

I'll leave the details up to you, but that might be a workable solution to your problem. Do you think that might work?
