PHP Date Exercises : Check whether a date is a weekend or not

PHP date: Exercise-15 with Solution

Write a PHP script to check whether a date is a weekend or not.

Sample Solution:

PHP Code:

<?php
$dt='2011-01-04'; // Assigning the date '2011-01-04' to the variable $dt.
$dt1 = strtotime($dt); // Converting the date string to a Unix timestamp and storing it in $dt1.
$dt2 = date("l", $dt1); // Formatting the Unix timestamp $dt1 to retrieve the day of the week in full textual representation (e.g., 'Monday') and storing it in $dt2.
$dt3 = strtolower($dt2); // Converting the day of the week to lowercase and storing it in $dt3.

if (($dt3 == "saturday") || ($dt3 == "sunday")) { // Checking if the day is Saturday or Sunday.
    echo $dt3.' is weekend'."\n"; // Outputting that it's a weekend if the day is Saturday or Sunday.
} else {
    echo $dt3.' is not weekend'."\n"; // Outputting that it's not a weekend if the day is not Saturday or Sunday.
}
?>

Output:

tuesday is not weekend

Explanation:

In the exercise above,

• $dt='2011-01-04';: Assigning the date '2011-01-04' to the variable '$dt'.
• $dt1 = strtotime($dt);: Converting the date string stored in '$dt' to a Unix timestamp and storing it in the variable '$dt1'.
• $dt2 = date("l", $dt1);: Formatting the Unix timestamp stored in '$dt1' to retrieve the day of the week in full textual representation (e.g., 'Monday') and storing it in the variable '$dt2'.
• $dt3 = strtolower($dt2);: Converting the day of the week stored in '$dt2' to lowercase and storing it in the variable '$dt3'.
• Checking if the day stored in '$dt3' is Saturday or Sunday using an if-else statement.
• Outputting whether the day is a weekend day or not based on the result of the if-else condition.
