PHP - Change A Date To A Different Date Based On Timezone..

I'm working on a project that has a lot of different timezone options, and all I have from the users is their UTC offset.

After weeks of doing tweaks, I come to new issues every time I add something, one would think it would be a lot easier to just get the correct time and day :)

The latest issue is that when I try to rewrite a date to a better fomat, it disregards the GMT offset. Like this:

4/14/19, 12:00 PM GMT+2 (=$date) becomes ... 14-04-2019 10:00 when using this code:

$bp_date_to_format = date_create_from_format('Y-m-d\TH:i:sP', $date);
echo date_format($bp_date_to_format, 'd-m-Y H:i');

I figured it would just rewrite the format, keeping the exact time. It isn't.

We do have all these sorts of localization functions as well, but because there doesn't seem to be one single standard (each 3rd party API connection we have uses its own default datetime format so it seems).

        // Remove UTC Text
        $UTC_offset = str_replace('UTC', '', $timezone);

        // Get Offset in Minutes
        if (stripos($UTC_offset, ':') !== false) {
            // Calculate seconds from offset
            list($hours, $minutes) = explode(':', $offset);
            $seconds = $hours * 60 * 60 + $minutes * 60;
        } else {
            $seconds = $UTC_offset * 60 * 60;
        }

        // Get User timezone name from seconds
        $timezone = timezone_name_from_abbr('', $seconds, 1);
        if ($timezone === false) {
            $timezone = timezone_name_from_abbr('', $seconds, 0);
        }
        // Set new TZ
        return date_default_timezone_set($timezone);

 

Isn't there any "one way"solution that can be used? It's confusing to say the least.

 

Cheers.

Ok well i have a virtual world, my friendcoded the emulator. In PHP but he's on holiday for 2 weeks. I keep getting

But there are only 4 lines in chapatiz.php and it has nothing to do with it i think

I have no clue whats wrong it use to work.

Hey,

I'm using a script which allows you to click on a calendar to select the date to submit to the database.

The date is submitted like this: 2014-02-08

Is there a really simple way to prevent rows showing if the date is in the past?

Something like this:
if($currentdate < 2014-02-08 || $currentdate == 2014-02-08) {

}

Thanks very much,
Jack

I would really appreciate help and I hope my problem can be solved easily. I am attempting to display the date/time based on the user's location. I have installed the timezone.js plugin for help as well. Is there a way to convert the Jquery variable that displays the users timezone location and insert it inside the PHP date_default_timezone_set?   If there is an easier way to display the users timezone date and time please let me know otherwise this was the only solution I could find.   Thanks in advanced...   Here is my code   Header

<header>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js"></script>
<script src="Time/detect_timezone.js"></script>
<script src="Time/jquery.detect_timezone.js"></script>
<script>
$(document).ready(function(){
  $('#tzvalue').set_timezone({'default' : 'America/Los_Angeles'});
});
</script>
</header>

 

I need to know which day of week was on particular date, so for example I would provide date lets say "Nov 22, 2010" formatted as needed and the function would return "Monday", is there a function in php to do that or how can it be done?
