The this instead. BTW, you misunderstood the useage of substr, see
http://uk.php.net/manual/en/function.substr.php.

$code = 'abcdwxyz8765';
$string = array();
array_push($string,substr($code,0,4));
array_push($string, substr($code,4,4));
array_push($string, substr($code,8,4));
echo $string[0].'-'.$string[1].'-'.$string[2];

Very very nasty code :/

Here ya go: implode('-', str_split('abcdwxyz8765', 4));
Test:
C:\>php -r "echo implode('-', str_split('abcdwxyz8765', 4));"
abcd-wxyz-8765
