Date Helper

The Date Helper file contains functions that assist in working with dates.

Loading this Helper

This helper is loaded using the following code:

<?php

helper('date');

Available Functions

The following functions are available:

now([$timezone = null])

Parameters

• $timezone (string) – Timezone

Returns

UNIX timestamp

Return type

int

Returns the current time as a UNIX timestamp, referenced either to your server’s local time or any PHP supported timezone, based on the “time reference” setting in your config file. If you do not intend to set your master time reference to any other PHP supported timezone (which you’ll typically do if you run a site that lets each user set their own timezone settings) there is no benefit to using this function over PHP’s time() function.

<?php

echo now('Australia/Victoria');

If a timezone is not provided, it will return time() based on the time_reference setting.

timezone_select([$class = '', $default = '', $what = \DateTimeZone::ALL, $country = null])

Parameters

• $class (string) – Optional class to apply to the select field

• $default (string) – Default value for initial selection

• $what (int) – DateTimeZone class constants (see listIdentifiers)

• $country (string) –

  A two-letter ISO 3166-1 compatible country code (see listIdentifiers)

Returns

Preformatted HTML select field

Return type

string

Generates a select form field of available timezones (optionally filtered by $what and $country). You can supply an option class to apply to the field to make formatting easier, as well as a default selected value.

<?php

echo timezone_select('custom-select', 'America/New_York');

Many functions previously found in the CodeIgniter 3 date_helper have been moved to the I18n module in CodeIgniter 4.
