Last update on December 20 2024 10:18:47 (UTC/GMT +8 hours)

Write a PHP script to get the first and last day of a month from a specified date.

Sample Solution:

PHP Code:

<?php
$dt = "2008-02-23"; // Define the date string
echo 'First day : '. date("Y-m-01", strtotime($dt)).' - Last day : '. date("Y-m-t", strtotime($dt));  
?>

Output:

First day : 2008-02-01 - Last day : 2008-02-29

Explanation:

In the exercise above,

• $dt = "2008-02-23";: Specifies the date string "2008-02-23".
• strtotime($dt): Converts the date string to a Unix timestamp.
• date("Y-m-01", strtotime($dt)): Formats the Unix timestamp to display the first day of the month in the format "YYYY-MM-01".
• date("Y-m-t", strtotime($dt)): Formats the Unix timestamp to display the last day of the month in the format "YYYY-MM-t", where "t" represents the number of days in the given month.
• echo 'First day : '. date("Y-m-01", strtotime($dt)).' - Last day : '. date("Y-m-t", strtotime($dt));: Prints the formatted first and last days of the month.
