When faced with the task of printing the final day of a given month in PHP, you can achieve this by utilizing the date() and strtotime() functions. Employing these functions allows for a seamless retrieval of the last day of the month based on a provided date.
Used PHP functions:
-
The
date()function in PHP is utilized to format a local time or date according to specified parameters. -
The
strtotime()function in PHP is employed to parse nearly any English textual datetime description and convert it into a Unix timestamp.
Examples:
Input: 2020-04-23
Output: Thursday
Input: '2018-09-11'
Output: Sunday
Approach:
- When provided with a date stored as a string in a variable, the process involves converting it into a date format using the
strtotime()function. - After obtaining the date, we will utilize the
date()method.
Syntax:
date( $format, $timestamp )
- Within the
$format, we will pass 'Y-m-t', and within$timestamp, the date obtained earlier. In terms of the date format, 'Y' represents a full numeric representation of a year in four digits, 'm' provides a numeric representation of a month, and 't' gives the number of days in the given month. - Utilizing 'Y-m-t', we can retrieve the number of days in a month, as 't', 'm', and 'Y' respectively represent the day, month, and year components of the date.
- The final step involves once again using the
date()function, this time with 'l' as the format, and the previously obtained date as the$timestamp. - Display the day.
Program:
<?php
// Given a date in string format
$datestring = '2020-04-23';
// Converting string to date
$date = strtotime($datestring);
// Last date of current month.
$lastdate = strtotime(date("Y-m-t", $date ));
// Day of the last date
$day = date("l", $lastdate);
echo $day;
?>
Output:
Thursday
