How to set time zone in codeigniter?

Question

I am working in a php project using codeigniter. Please advise me what is the global way to set time zone for php and mysql . In which file I can set this. I want to set it

Answer 1

Put it in config/config.php, It will work for whole application or index.php of codeigniter.

Answer 2

you can try this:

date_default_timezone_set('Asia/Kolkata');

In application/config.php OR application/autoload.php

There is look like this:

<?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');

date_default_timezone_set('Asia/Kolkata');

It's working fine for me, i think this is the best way to define DEFAULT TIMEZONE in codeignitor.

Answer 3

Placing this date_default_timezone_set('Asia/Kolkata'); on config.php above base url also works

PHP List of Supported Time Zones

application/config/config.php

<?php

defined('BASEPATH') OR exit('No direct script access allowed');

date_default_timezone_set('Asia/Kolkata');

Another way I have found use full is if you wish to set a time zone for each user

Create a MY_Controller.php

create a column in your user table you can name it timezone or any thing you want to. So that way when user selects his time zone it can can be set to his timezone when login.

application/core/MY_Controller.php

<?php

class MY_Controller extends CI_Controller {

    public function __construct() {
        parent::__construct();
        $this->set_timezone();
    }

    public function set_timezone() {
        if ($this->session->userdata('user_id')) {
            $this->db->select('timezone');
            $this->db->from($this->db->dbprefix . 'user');
            $this->db->where('user_id', $this->session->userdata('user_id'));
            $query = $this->db->get();
            if ($query->num_rows() > 0) {
                date_default_timezone_set($query->row()->timezone);
            } else {
                return false;
            }
        }
    }
}

Also to get the list of time zones in php

 $timezones =  DateTimeZone::listIdentifiers(DateTimeZone::ALL);

 foreach ($timezones as $timezone) 
 {
    echo $timezone;
    echo "</br>";
 }

Answer 4

As describe here

1. Open your php.ini file (look for it)

2. Add the following line of code on the top of the file:

   date.timezone = "US/Central"

3. Verify the changes by going to phpinfo.php

Answer 5

Add this line to autoload.php in the application folder:

$autoload['time_zone'] = date_default_timezone_set('Asia/Kolkata');
