What are some alternative methods for achieving the desired outcome in the PHP script?

Issue: The current PHP script uses a loop to iterate over an array and perform a specific action on each element. However, there are alternative methods that can achieve the same outcome more efficiently, such as using array_map or array_walk. Alternative method using array_map:

// Original code using a loop
$array = [1, 2, 3, 4, 5];
foreach ($array as $value) {
    // Perform some action on $value
}

// Alternative method using array_map
$newArray = array_map(function($value) {
    // Perform the same action on $value
    return $value;
}, $array);
```

Alternative method using array_walk:

```php
// Original code using a loop
$array = [1, 2, 3, 4, 5];
foreach ($array as &$value) {
    // Perform some action on $value
}
unset($value); // Unset the reference variable

// Alternative method using array_walk
array_walk($array, function(&$value) {
    // Perform the same action on $value
});
