I am trying to use the date() function as an alternative to the now deprecated strftime() function, and I need to know whether the date() function formats the time like the strftime() function according to the locale time.

strftime()

As said by php.net in the strftime() manual:

strftime — Format a local time/date according to locale settings

But in the date() function manual date() it only says:

date — Format a Unix timestamp

So does it format the Unix timestamp to the locale settings?

Welcome on StackOverflow.

Date formats a Unix timestamp. Unix timestamp means seconds from epoch. Epoch is the Thursday, 01 January 1970 00:00:01.000 Where I live (CET), this is the Thursday, 01 January 1970 00:00:01.000 01:00, so it depends on your locale

echo date(DATE_RFC2822,0); //return Thu, 01 Jan 1970 00:00:00  0000

But if you set your locale, result is different:

date_default_timezone_set('CET');
echo date(DATE_RFC2822,0); //return Thu, 01 Jan 1970 00:00:00  0100

About the languages, this method does not use "locales". All outputs are in English.

You already linked the perfect source for information on that matter.

The format information on the date() docs page points to the DateTimeeInterface::format page (https://www.php.net/manual/en/datetime.format.php) that states:

This method does not use locales. All output is in English.
