Get user timezone string with Javascript / PHP?
php, timezone
Solution
You can't do this in PHP alone.
You can use Javascript to set the value in a cookie, then use PHP to read the cookie on the next page (re)load.
Javascript:
var dateVar = new Date()
var offset = dateVar.getTimezoneOffset();
document.cookie = "offset="+offset;
PHP:
echo $_COOKIE['offset'];
Use this to convert the offset to the friendly timezone name in PHP. Javascript returns the offset in minutes, while this PHP function expects the input to be in seconds - so multiply by 60. The third parameter is a boolean value of whether or not you are in Daylight Savings Time. Read the manual and update the code to fit your needs.
echo timezone_name_from_abbr("", intval($_COOKIE['offset'])*60, 0);

Problem
I'm trying to get the user's timezone as a string on singup. example: ``` $timezone = "Asia/Tel_Aviv"; ``` While researching the issue, I got how to Get timezone offset with Javascript, but I'm still unclear about how can I translate the timezone offset to a timezone string in php, as shown above? Or, which other method cas I use in Javascript / PHP for getting the timezone string for each user? I'm really not sure how to approach this.
