10. Validate Given Dates

Write a PHP script to check whether the given dates are valid or not?

Sample Solution:

PHP Code:

<?php
var_dump(checkdate(2, 30, 2008)); // Checks if the given date (February 30, 2008) is valid.
var_dump(checkdate(2, 29, 2008)); // Checks if the given date (February 29, 2008) is valid.
?>

Output:

bool(false)                                                 
bool(true)

Explanation:

In the exercise above,

checkdate(2, 30, 2008): Checks if the date February 30, 2008 is a valid date.
checkdate(2, 29, 2008): Checks if the date February 29, 2008 is a valid date (2008 was a leap year, so February 29 is valid).
