PHP Exercises: Check if one of the first 4 elements in an array of integers is equal to a given element

PHP Basic Algorithm: Exercise-33 with Solution

Write a PHP program to check if one of the first 4 elements in an array of integers is equal to a given element.

Sample Solution:

PHP Code :

<?php
// Define a function that checks if a given number is present in an array of numbers
function test($nums, $n)
{
    // Use the sizeof function to check the size of the array and determine the range for in_array
    return sizeof($nums) < 4 ? in_array($n, $nums) : in_array($n, array_slice($nums, 0, 4));
}

// Test the function with different arrays and numbers
var_dump(test(array(1,2,9,3), 3));
var_dump(test(array(1,2,3,4,5,6), 2));
var_dump(test(array(1,2,2,3), 9));
?>

Sample Output:

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