PHP Date - What is a Timestamp?
The timestamp is the number of seconds since January 1, 1970 (00:00:00 GMT). It is also known as Unix Timestamp.
PHP Date - formatted date
The first parameter of the date() function specifies how to format the date/time. It uses letters to represent the format of date and time. Here are some available letters:
- d - day of the month (01-31)
- m - the current month, as a number (01-12)
- Y - the current year (four digits)
You can find all the letters that can be used in format parameters in our PHP Date reference manual.
Additional characters such as "/", ".", or "-" can be inserted between letters to add additional formatting:
<?php
echo date("Y/m/d");
echo "<br />";
echo date("Y.m.d");
echo "<br />";
echo date("Y-m-d");
?>
The output of the above code looks like this:
2006/07/11 2006.07.11 2006-07-11
PHP Date - Add Timestamp
The second parameter of the date() function specifies a timestamp. This parameter is optional. If you don't provide a timestamp, the current time will be used.

The mktime() function returns a Unix timestamp for the specified date.
