Solution using preg_match_all function and POSIX character class [:xdigit:](will match all hexadecimal digits):

// $str is your initial string
preg_match_all("/\b[[:xdigit:]]{2}-[[:xdigit:]]{2}-[[:xdigit:]]{2}-[[:xdigit:]]{2}-[[:xdigit:]]{2}-[[:xdigit:]]{2}\b/su", $str, $matches);

print_r($matches[0]);

The output:

Array
(
    [0] => 00-1F-29-A8-CA-54
    [1] => 00-21-5C-68-BB-17
)
