New line in PHP array

Question

Doing print_r on my array produces:

Array
(
    [0] => dogs
    [1] => cats

    [2] => birds
)

The newline between cats and birds is causing a problem. I did the following and the spacing still persists: array_walk($arr,'trim');

What can be done to remove this spacing?

Most probably you have forgotten a new line in the cats entry. — linkyndy

array_walk returns a boolean. Use array_map instead:

$arr = array_map("trim", $arr);

array_walk won't help you, since it does not by itself persist any changes to the data. Use array_map instead:

$arr = array_map('trim', $arr);

If possible you should eliminate that extraneous line break from the beginning though, not filter it out after the fact.
