timestamp formats

[Destramic]

im trying to format a timestamp, for instance if date is today then it will return today then [time] and if date is yesterdays date then it will return it...I want it to work in different time zones, but im having a bit of trouble gettin it all together and working...can somone have a look and gove me some pointers?

 

<?php

timestamp_format($timestamp, $format = “d/m/Y G: i:s T”, $time_zone = “GMT”)
{
	date_default_timezone_set($time_zone);

$timestamp       = expload(“ “, date($format, $timestamp));
      $yesterdays_date = ;
$todays_date     = date($format, $timestamp[0]);

if ($timestamp[0] == $todays_date)
{
	$date = “Today at ” . $timestamp[1];
}
else if ()
{
	$date = “Yesterday at ” .$timestamp[1];
}
else
{
	$date = $timestamp[0] . $timestamp[1];
}

return $date;
}

?>

First, you're using "smart quotes" “ ”. They don't work with PHP. Use only normal single or double quotes.

 

You didn't tell PHP that your function was a function.

 

Here's a version of your code that works. I included three test cases at the bottom of the script:

<?php

function timestamp_format($timestamp, $format = 'd/m/Y G:i:s T', $time_zone = 'GMT')
{
	date_default_timezone_set($time_zone);
$today = date('Y-m-d');
$yesterday = date('Y-m-d',strtotime('yesterday'));
$test_date = date('Y-m-d',$timestamp);
$time_part = explode(' ',$format,2);

switch (true) {
case ($test_date == $today):
	$date = 'Today at ' . date($time_part[1],$timestamp);
	break;
case ($test_date == $yesterday):
	$date = 'Yesterday at ' . date($time_part[1],$timestamp);
	break;
default:
	$date = date($format,$timestamp);
}
return $date;
}

echo timestamp_format(time()).'<br>';
echo timestamp_format(strtotime('yesterday')).'<br>';
echo timestamp_format(strtotime('-2 days'));

?>

I want it to work in different time zones

 

don't understand this. If you are in UK and you get a hit from someone in australia, the time will still

be the time on your UK server, but will probably say 4am. are you trying to get a time from another country?

basically if $time_zone = "umt" or something different i want the time to show up in that time zone.

You would have to use either a very complicated ip location script to get the timezone based on ip location or javascript to get the time on the users comuter.

 

Since php exists only on the server, the time would have to come from a  use of startoftime adjusted for the timezone differences on the users end. The only way to do that would be to make them set their timezone using sessions and then doing the startoftime adjustments from there.

 

Or just use a central timezone and report that on the page like 12:00 am (GMT)

 

I think that most people could figure it out.

i would change the time zone using this function

 

date_default_timezone_set($time_zone);

 

all the timezones would come from the database, i have a colum which tells me the users timezone and then i change the time zone accordingly

[per1os]

// timezone is Mountain (-7)
$time = time()+3600*-7;

 

The time would than be displayed -7 hours. You have to do that with every time you want to display. You would need strictly the offset to accomplish this.

[Destramic]

bah i thought this could simply be done via

date_default_timezone_set($time_zone);

 

have a page which could help me out?

[rcorlew]

Could you just insert the time using a timestamp generated by php, then to make it easier for the users to understand how long ago that was to a time comparison to the current time.

 

THe comparison would make it look something like this:

 

Posted ----->4 hours and 30 minutes ago<---------- 1:43 pm (GMT)

 

That may be the best and easiest way to do what you are wanting to do I think.
