Regarding the method of obtaining time through PHP, we have introduced several methods in previous articles, one of which is "PHP Date and Time Application Five: Obtaining the Current Date/Time in Different Time Zones" If you are interested, you can find out~

So the topic of today’s article is slightly different from the previous method of obtaining time, because this article not only introduces how to obtain the date but also the specific time of the week. Of course, it is not difficult. , let’s introduce it in detail below!

First open the PHP editor and create a PHP sample file;

Then we add the code:

<?php
$old_Locale = setlocale(LC_TIME, &#39;US&#39;);
echo  strftime("Today is %a on %b %d, %Y")."\n";
setlocale(LC_TIME, $old_Locale);
Copy after login

The output result is:

PHP date and time application 7: Get the date and day of the week in a certain country

In other words, "Today is Wednesday, August 4, 2021."

In this code, we use the setlocale function to set the region where we want to obtain date information to the United States; then we use the strftime function to format the local date and time according to the regional settings.

Here you need to understand a key function strftime(). Mastering the parameters in this function can help you quickly obtain the time information you want;
