Here are some characters commonly used for dates:
d - represents the day of the month (01-31)
m - represents the month (01-12)
Y - represents the year (four digits)
1 - represents the week
Other characters, such as "/", "." or "-" can also be inserted into the characters to add other formatting.

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

How do I embed PHP code in an HTML file?
Jun 22, 2025 am 01:00 AM
You can embed PHP code into HTML files, but make sure that the file has an extension of .php so that the server can parse it correctly. Use standard tags to wrap PHP code, insert dynamic content anywhere in HTML. In addition, you can switch PHP and HTML multiple times in the same file to realize dynamic functions such as conditional rendering. Be sure to pay attention to the server configuration and syntax correctness to avoid problems caused by short labels, quotation mark errors or omitted end labels.
