50. Get Last Array Value Without Affecting Pointer

Write a PHP script to get the last value of an array without affecting the pointer.

Sample Solution:

PHP Code:

<?php
// Original associative array
$colors = array('c1' => 'Red',  'c2' => 'Green',  'c3' => 'White',  'c4' => 'Black');
// Move the internal pointer to the next element and return its value
echo next($colors) . "\n";
// Use array_flip to swap keys and values, then array_keys to get the keys
$keys = array_keys(array_flip($colors));
// Use array_pop to get the last element
$last = array_pop($keys);
echo $last . "\n";
// Move the internal pointer to the first element and return its value
echo current($colors) . "\n";
  
?>

Output:

Green                                                       
Black                                                       
Green
