PHP Exercises: Check a given array of integers of length 1 or more and return true if 10 appears as either first or last element in the given array

PHP Basic Algorithm: Exercise-86 with Solution

Write a PHP program to check a given array of integers of length 1 or more and return true if 10 appears as either first or last element in the given array.

Sample Solution:

PHP Code :

<?php
// Define a function named 'test' that checks if the first or the last element of an array is equal to 10
function test($nums)
{ 
    // Check if the first element of the array is equal to 10 or the last element is equal to 10
    return $nums[0] == 10 || $nums[sizeof($nums) - 1] == 10;
}

// Test the 'test' function with different arrays, then display the results
var_dump(test([10, 20, 40, 50]));
var_dump(test([5, 20, 40, 10]));
var_dump(test([10, 20, 40, 10]));
var_dump(test([12, 24, 35, 55]));
?>

Sample Output:

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