Write a PHP program to check if a given array of integers and length 2, does not contain 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 not equal to 15 and not equal to 20,
    // and the second element is not equal to 15 and not equal to 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:
• $nums: an array of numbers.
• Return Condition:
• The function checks if:
• The first element of the array ($nums[0]) is not equal to 15 and not equal to 20.
• The second element of the array ($nums[1]) is not equal to 15 and not equal to 20.
• If all these conditions are true, the function returns true; otherwise, it returns false.

Output:

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