PHP - trim array elements value without foreach [duplicate]

Question

I am using following code in php: Code:

$input = array("     text1","text2      "," text3       ","     text4");
$output = array();
foreach($input as $val)
     {
        $output[] = trim($val);
     }
var_dump($output);

Is it possible to trim array elements value without foreach loop?

Answer 1

You can use array_map:

$output = array_map('trim', $input);

Of course this will still iterate over the array internally.

Answer 2

This should work just fine;

$input = array("     text1","text2      "," text3       ","     text4");
$output = array_map('trim', $input);
var_dump($output);
