PHP Basic Algorithm: Exercise-94 with Solution
Write a PHP program to create a new array taking the first and last elements of a given array of integers and length 1 or more.
Sample Solution:
PHP Code :
<?php
// Define a function named 'test' that takes an array of numbers as a parameter
function test($nums)
{
// Return a new array containing the first and last elements of the input array
return [$nums[0], $nums[sizeof($nums) - 1]];
}
// Create an array $a with some numeric values
$a = [10, 20, -30, -40, 30];
// Print the original array as a string using 'implode' and 'echo'
echo "Original array: " . implode(',', $a) . "\n";
// Call the 'test' function with the array $a and store the result in $result
$result = test($a);
// Print the new array containing the first and last elements using 'implode' and 'echo'
echo "New array: " . implode(',', $result);
?>
Sample Output:
Original array: 10,20,-30,-40,30 New array: 10,30
