PHP Date and Time


The PHP date() function is used to format a date and/or a time.


The PHP Date() Function

The PHP date() function formats a timestamp to a more readable date and time.

date(format,timestamp)

The example below formats today's date in three different ways:

<?php
    echo "Today is " . date("Y/m/d") . "<br>";
    echo "Today is " . date("Y.m.d") . "<br>";
    echo "Today is " . date("Y-m-d") . "<br>";
    echo "Today is " . date("l");
?>

Get a Simple Time

<?php
    echo "The time is " . date("h:i:sa");
?>

Get Your Time Zone

If the time you got back from the code is not the right time, it's probably because your server is in another country or set up for a different timezone. So that to get your country time or correct time according to your country then you must set timezone.

<?php
    date_default_timezone_set("America/New_York");
    echo "The time is " . date("h:i:sa");
?>
