PHP Exercises: Rotate the elements of a given array of integers in left direction and return the new array
PHP Basic Algorithm: Exercise-90 with Solution
Write a PHP program to rotate the elements of a given array of integers (length 4 ) in left direction and return the new array.
Sample Solution:
PHP Code :
<?php
// Define a function named 'test' that rotates the elements of the given array.
function test($a1)
{
// Return a new array with elements rotated by one position to the left.
return [$a1[1], $a1[2], $a1[3], $a1[0]];
}
// Create an array $a with initial values.
$a = [10, 20, -30, -40];
// Display the original array.
echo "Original array: " . implode(',', $a) . "\n";
// Call the 'test' function to rotate the array elements.
$result = test($a);
// Display the rotated array.
echo "Rotated array: " . implode(',', $result);
?>
Sample Output:
Original array: 10,20,-30,-40 Rotated array: 20,-30,-40,10
