What are the potential benefits of using array_map in PHP for trimming values stored in an array?

When working with an array in PHP, you may need to trim all the values stored in the array to remove any leading or trailing whitespace. One way to achieve this is by using the `array_map` function in PHP. `array_map` allows you to apply a callback function to each element of an array, in this case, the `trim` function can be used to remove whitespace from each value in the array. 

// Sample array with values containing whitespace
$array = ['  apple ', 'banana  ', '  cherry  '];

// Using array_map with trim to remove whitespace from all values
$array = array_map('trim', $array);

// Output the trimmed array
print_r($array);
