PHP Exercises: Create a new array taking the first two elements from a given array

PHP Basic Algorithm: Exercise-105 with Solution

Write a PHP program to create a new array taking the first two elements from a given array. If the length of the given array is less than 2 then return the give array.

Sample Solution:

PHP Code :

<?php
// Define a function named 'test' that takes an array of numbers as a parameter
function test($numbers)
 { 
    // Check if the size of the array is greater than or equal to 2
    if (sizeof($numbers) >= 2)
    {
        // If true, create a new array $front_nums with the first two elements of $numbers
        $front_nums = [$numbers[0], $numbers[1]];
    }
    // Check if the size of the array is greater than 0 (but less than 2)
    else if (sizeof($numbers) > 0)
    {
        // If true, create a new array $front_nums with the first element of $numbers
        $front_nums = [$numbers[0]];
    }
    // If the array is empty
    else
    {
        // Create an empty array $front_nums
        $front_nums = [];
    }

    // Return the array $front_nums
    return $front_nums;
 }   

// Call the 'test' function with an array [1, 5, 7, 9, 11, 13] and store the result in $result
$result = test([1, 5, 7, 9, 11, 13]);

// Print the new array $front_nums using 'implode' and 'echo'
echo "New array: " . implode(',', $result);
?>

Sample Output:

New array: 1,5
