The date () function of PHP is used to format the time or date.

PHP Date-What is a timestamp (Timestamp)?

The timestamp is the number of seconds since January 1, 1970 (00:00:00 GMT). It is also known as the Unix timestamp (Unix Timestamp).

PHP Date-formatted date

The first parameter of the date () function specifies how the date/time is formatted. It uses letters to represent the format of dates and times. Some of the available letters are listed here:

• D-Day of the month (01-31)
• M-Current month, measured in digital (01-12)
• Y-Current year (four digits )

You can find all the letters you can use in the format parameters in our PHP Date reference manual.

You can insert additional characters between letters, such as "/", ".", or "-" to add additional formatting:

 
  echo Date ("Y.M.D"); echo "
"; Echo Date (" y-m-d ");? >

The output of the above code is similar to this:

2006/07/112006.07.112006-07-11

PHP Date-Add timestamp

The second parameter of the date () function specifies a timestamp. This parameter is optional. If you do not provide a timestamp, the current time will be used.

In our example, we will use the mktime () function to create a timestamp for tomorrow.

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

Grammar

Mktime (Hour,minute,second,month,Day, YEAR,IS_DST)

To get a timestamp for a given day, we just set the Mktime () function to the time parameter :

 
  , Date ("D") +1,date ("Y")); echo "Tomorrow is." Date ("y/m/d", $tomorrow);? >

The output of the above code is similar to this:

Tomorrow is 2006/07/12.
