How can I explode and trim whitespace?

For example, I would like to create an array from the elements in this string:

$str = 'red, green, blue ,orange';


I know you can explode and loop through them and trim:

$arr = explode(',', $str);
foreach ($arr as $value) {
$new_arr[] = trim($value);
}


But I feel like there's a one line approach that can handle this. Any ideas?

Answer

You can do the following using array_map:

$new_arr = array_map('trim', explode(',', $str));
