PHP date and time application 7: Get the date and day of the week in a certain country
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, 'US');
echo strftime("Today is %a on %b %d, %Y")."\n";
setlocale(LC_TIME, $old_Locale);The output result is:
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;

The following is the organized strftime parameter information:
%a - 星期几名称的简写 %A - 星期几名称的全称 %b - 月份名称的简写 %B - 月份名称的全称 %c - 首选的日期和时间表示法 %C - 表示世纪的数字（年份除以 100，范围从 00 到 99） %d - 一个月中的第几天（01 到 31） %D - 时间格式，与 %m/%d/%y 表示法相同 %e - 一个月中的第几天（1 到 31） %g - 与 %G 表示法类似，但不带世纪 %G - 与 ISO 星期数对应的 4 位数年份（见 %V） %h - 与 %b 表示法相同 %H - 小时，使用 24 小时制（00 到 23） %I - 小时，使用 12 小时制（01 到 12） %j - 一年中的第几天（001 到 366） %m - 月份（01 到 12） %M - 分 %n - 换行符 %p - 与给定的时间值相对应的 am 或 pm %r - a.m. 和 p.m. 的时间标记法 %R - 24 小时制的时间标记法 %S - 秒 %t - tab 制表符 %T - 当前时间，与 %H:%M:%S 表示法相同 %u - 星期几的数字表示（1 到 7），Monday[星期一] = 1。警告：在 Sun Solaris 系统中，Sunday[星期日] = 1 %U - 当年包含的周数，从第一个星期日开始，作为第一周的第一天 %V - 当年包含的 ISO 8601 格式下的周数（01 到 53），week 1 表示当年的第一周，至少要有四天，且以星期一作为周的第一天 %W - 当年包含的周数，从第一个星期一开始，作为第一周的第一天 %w - 以十进制数形式表示一周中的某天，Sunday[星期日] = 0 %x - 首选的日期表示法，不带时间 %X - 首选的时间表示法，不带日期 %y - 不包含表示世纪的数字的年份表示（范围从 00 到 99） %Y - 包含表示世纪的数字的年份表示 %Z 或 %z - 时区名称或简写 %% - 输出一个 % 字符
