In what scenarios would using array_map function be more appropriate than manually iterating over an array in PHP?

Using the array_map function in PHP is more appropriate than manually iterating over an array when you need to apply a callback function to each element of an array and return a new array with the modified values. It can simplify your code and make it more readable by abstracting the iteration process. 

// Example: Using array_map to square each number in an array
$numbers = [1, 2, 3, 4, 5];

// Using array_map to square each number
$squaredNumbers = array_map(function($num) {
    return $num * $num;
}, $numbers);

print_r($squaredNumbers);
```

Output:
```
Array
(
    [0] => 1
    [1] => 4
    [2] => 9
    [3] => 16
    [4] => 25
)
