95. Array Contains 15 or 20 Check

Write a PHP program to check if a given array of integers and length 2, contains 15 or 20.

Sample Solution:

PHP Code :

<?php
// Define a function named 'test' that takes an array of numbers as a parameter
function test($nums)
 { 
    // Return true if the first element is equal to 15 or 20, or if the second element is equal to 15 or 20
    return $nums[0] == 15 || $nums[0] == 20 || $nums[1] == 15 || $nums[1] == 20;
 }   

// Check and display the result of calling 'test' with the array [12, 20]
var_dump(test([12, 20]));

// Check and display the result of calling 'test' with the array [14, 15]
var_dump(test([14, 15]));

// Check and display the result of calling 'test' with the array [11, 21]
var_dump(test([11, 21]));
?>

Explanation:

Function Definition:

A function named test is defined, which takes one parameter:

$nums: an array of numbers.

Return Condition:

The function checks whether:

The first element of the array ($nums[0]) is equal to 15 or 20.
The second element of the array ($nums[1]) is equal to 15 or 20.

If any of these conditions is true, the function returns true; otherwise, it returns false.

Output:

bool(true)
bool(true)
bool(false)
