Write a PHP script to find earliest and latest dates from a list of dates.

Visual Presentation:

Sample Solution:

PHP Code:

<?php
$dates = array('2015-02-01', '2015-02-02', '2015-02-03'); // Define an array of dates

// Print the latest date from the array
echo "Latest Date: " . max($dates) . "\n";

// Print the earliest date from the array
echo "Earliest Date: " . min($dates) . "\n";
?>

Output:

Latest Date: 2015-02-03                                     
Earliest Date: 2015-02-01

Explanation:

In the exercise above,

• $dates = array('2015-02-01', '2015-02-02', '2015-02-03');: This line initializes an array '$dates' containing three date strings.
• echo "Latest Date: " . max($dates) . "\n";: This line finds the maximum (latest) date from the array '$dates' using the "max()" function and then prints it along with the label "Latest Date".
• echo "Earliest Date: " . min($dates) . "\n";: This line finds the minimum (earliest) date from the array '$dates' using the "min()" function and then prints it along with the label "Earliest Date".
