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:
Copy the Code code as follows:
echo Date ("y/m/d");
echo "
";
echo Date ("Y.M.D");
echo "
";
echo Date ("y-m-d");
?>
