Timezone

[html="html4strict"]
<p>Hi Prof, i would like to know about: The timezone this server is located in is, I must code our country as South Africa? because I assume the server is located in Unisa. Please Prof, Course Mate to advise, about to complete an assignment. The code that I am sure about is: The timezone I live in is: Africa/Johannesburg.

Thanks You.</p>

The timezone the server is located in refers to the actual server where your assignment website is being hosted, so it could potentially be anywhere in the world. This shouldn't be hard-coded but needs to be dynamically picked up from the server itself.

A hint would be to have a look at the PHP date() function and it's various options.

Just try using the date function. 


date('H:i:s'winking smiley;

This will automatically pic the time zone according to your local machine, which is the time zone you live in.

WIth regard to server time zone, I did use ini.servername which is zymic but have been presented by an unusual date which I'm not sure if this is the correct way of displaying the server time zone. 
date('zymic.ini'winking smiley;
.
output: 2371308432013-08-26T11:43:03+02:00.43843

I would like again to find out how to display the previous date, in this case the date four days ago.

@Nathaniel...

The date function returns an integer value... so you can apply operators as per usual

@Nathaniel 

Language: PHP
date(';H:i:s';);

The value returned by this isn't really directly connected to any one specific timezone at all, but to all of them in a sense. Time != Timezone if that helps at all.

Also, that command will return the requested information related to the server, not the client, since PHP is a server side code. While testing your code through your local EasyPHP servers it would appear that the above code returns your clients' date/time info, but only because your "webserver" and "client" is actually the exact same system. Once you move the code to a host on the web it'll be easier to pick up on this.

You can determine the default Timezone with - 

Language: PHP
echo date_default_timezone_get();



and set the default Timezone with - 

Language: PHP
date_default_timezone_set(DONT POST COMPLETE CODE!);

Hi, can anyone help me on how to display the date four days ago. This should be a previous date.
I could not be able to display this.
I tried to display it using: 


mktime (date('D - 4'winking smiley, date('F d,Y'winking smiley);

But could not get the right results. The output was nothing, however I received the following error:

Warning: mktime() expects parameter 1 to be long, string given in C:\Users\41110641\Documents\EasyPHP-DevServer-13.1VC9\binaries\home\codesource.php on line 15

Use strtotime - (String to timestamp) 

Language: PHP
echo date(';d-m-Y';,strtotime("DONT POST COMPLETE CODE!"));



You can also look at DateTime add.

The file has to be .php - ie. index.php

Correct.

As a side note.... for some reason many students refer to me as a lecture.

From Wikipedia - a lecture is an oral presentation intended to present information or teach people about a particular subject, for example by a university or college teacher (lecturer) smiling smiley

So, going beyond my duties, as an educator... I am a lectureR smiling smiley

HI Guys,

After some googling and googling I had reach a conclusion that PHP does not include a function to get client timezone and it seems all people solution to this is to have JAVASCRIPT do the job for you. I might be wrong but guys if you have a solution to this please help me.

Thank you

Nyoka

@nyokahombe ,but with javascript i think you need to know basic ajex .i did it with javascript using cookies and the date() object but to write cookies with javascript and display them at the sametime using php you need to reload the page twice.

Hi Guys,

So assignment one its now gone and I am still here trying figure out how to get the client timezone as Mac have assured that there is function to do this in PHP and we need do more googling. I got this link http://www.justin-cook.com/wp/2006/11/29/determine-a-visitors-location-by-their-ip-address/ to share with you guys. It shows how to determine client location by IP address. It might not be the right way to get the timezone but its gets us closer.

Otherwise, we need to submit to Mac that we dont seem to be getting this function of getting client timezone and we could only ask a hint from him.

Thank you

Nyoka

The link you posted is about IP address - nothing to do with timezone. You simply have to Google ""get timezone of server PHP" and soemthing like "timezone difference PHP" to get and answer. The PHP manual has many function related to timezone
