Answer 1

You can use explode then preg_split

$arr = explode(':', $res);
$arr = preg_split('/\s+/', $arr[1]);
echo $arr[1];

You can also use this one with explode only.

$arr = explode("\n", $res);
$arr= explode(":", $arr[0]);
echo trim($arr[1]);

Answer 2

Trying Doing this

$arr = explode(':', $res);
$result = explode(' ', $arr[1]);
print_r($result[0]);

Answer 3

Try :

$ex = explode(":",$res);
$result = explode("\n",$ex[1]);
$result = $result[0];
echo trim($result); //echoes SUCCESS

Or :

$ex = explode("\n", $res);
$result = explode(":", $ex[0]);
$result = $result[1];
echo trim($result); //echoes SUCCESS

The first comment to your answer is the solution. But - for any reason - if you want to get all the keys and values, you can use preg_match for each line. A quick example:

<?php

$res = "RESULT: SUCCESS
NUMBER_TYPE:    0";

$arr = explode("\n", $res);

foreach($arr as $line)
{
    if(preg_match('/^([A-Z_]+):\s+?([a-zA-Z0-9_]+)$/', $line, $matches))
    {
        echo "Key: " . $matches[1] . " - Value: " . $matches[2] . "\n";
    }
}

Output:

Key: RESULT - Value: SUCCESS
Key: NUMBER_TYPE - Value: 0
