114. Contains 3 or 5 in Array Check

Write a PHP program to check if a given array of integers contains a 3 or a 5.

Sample Solution:

PHP Code :

<?php
// Define a function named 'test' that takes an array of numbers as a parameter
function test($nums)
 { 
    // Iterate through the elements of the array using a for loop
    for ($i = 0; $i < sizeof($nums); $i++)
    {
        // Check if the current element is not equal to 3 and not equal to 5, return false if true
        if ($nums[$i] != 3 && $nums[$i] != 5) return false;
    }

    // Return true if all elements are either 3 or 5, otherwise return false
    return true;
 }   

// Use 'var_dump' to print the result of calling 'test' with different arrays
var_dump(test([5, 5, 5, 5, 5]));
var_dump(test([3, 3, 3, 3]));
var_dump(test([3, 3, 3, 5, 5, 5]));
var_dump(test([1, 6, 8, 10]));
?>

Sample Output:

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