PHP filemtime time zoned-CodePudding

PHP coding question

How do I add DateTimeZone ('America/NewYork') to the PHP code at the end? I need my code to use filemtime. I included this footer.html in my main files so that all my website pages have the same footer. I also need the footer to filemtime the current file and not just header.html. If you know how to fix that too, please help me out.

<footer>

<div style="padding:0 30px">

<a href="https://validator.w3.org/check?uri=referer"><img src="https://www.w3.org/Icons/valid-xhtml11"

<p>Last modified:

<?php echo " ".date("F j Y g:i a.", filemtime("header.html")); ?>

</p>

</div>

</footer>

I tried rewritting the whole thing but nothing worked. As in nothing showing up at all or the time is 0:0.0

What you want, if I understand you correctly is to output the timestamp of filemtime("header.html") in the timezone of America/NewYork.

This is how you would do that:

$timestamp = filemtime("header.html");

$date_time = new DateTime();
$date_time->setTimezone(new DateTimeZone("America/New_York"));
$date_time->setTimestamp($timestamp);

echo $date_time->format("F j Y g:i a.");

Note that it is America/New_York and not America/NewYork.

If you want to display the filemtime of the current file you can use __FILE__:

$timestamp = filemtime(__FILE__);

filemtime() produces a Unix time, which is not subject to time zones (it's a fixed moment in time). All PHP functions that operate on Unix time and require a time zone (e.g. date()) read it from the global value. Such value can be set with the date.timezone directive or the date_default_timezone_set() function.
