下面我们来详细介绍下参数 $d ,即日期格式化字符串:(官方参考文档:http://codex.wordpress.org/Formatting_Date_and_Time)

Certain WordPress tag functions are used to display or return date and time information; the_date() and the_time() are examples of this. Some of these functions accept a parameter called a format string that allows you to determine how the date is going to be displayed. The format string is a template in which various parts of the date are combined (using “format characters”) to generate a date in the format specified.

For example, the format string:

l, F j, Y

creates a date that look like this:

Friday, September 24, 2004

Here is what each format character in the string above represents:

  • l = Full name for day of the week (lower-case L).
  • F = Full name for the month.
  • j = The day of the month.
  • Y = The year in 4 digits. (lower-case y gives the year’s last 2 digits)
(Commas are read literally.)

WordPress is written in the programming language PHP. The date formatting functions in WordPress use PHP’s built-in date formatting functions. You can use the table of date format characters on the PHP website as a reference for building date format strings for use in WordPress. Here is a table of some of the more useful items found there:

Day of Month
d Numeric, with leading zeros 01–31
j Numeric, without leading zeros 1–31
S The English suffix for the day of the month st, nd or th in the 1st, 2nd or 15th.
Weekday
l Full name  (lowercase ‘L’) Sunday – Saturday
D Three letter name Mon – Sun

m Numeric, with leading zeros 01–12
n Numeric, without leading zeros 1–12
