i`ve an array with more arrays inside.
But how can i get a specific value from it ?

[CLIENT] => Array

[ID] => 14
[FIRSTNAME] => John
[LASTNAME] => Doe
[COMPANYNAME] => Muster Company
[EMAIL] => info#mustermann.de
[DATECREATED] => 2014-04-13
[GROUPID] => 0
[STATUS] => Active

Answer 1

The other answers & comments are almost right, but they didn't notice that you're iterating over the array.
Here's your code:
foreach($arr as $result) {
echo $result['CLIENTS']['FIRSTNAME'];
}
Inside the loop (this is important), $result is equal to:
Array
(
[ACTION] => getclients
[RESULT] => success
[TOTALRESULTS] => 12
[STARTNUMBER] => 0
[NUMRETURNED] => 12
[CLIENTS] => Array
(
[CLIENT] => Array
(
...
So to access the client name inside the loop, use this:
$firstname = $result["CLIENTS"]["CLIENT"]["FIRSTNAME"];

You're missing a couple levels of the array. Try $result['WHMCSAPI']['CLIENTS']['CLIENT']['FIRSTNAME'].
