I have a 24-long string $string = "b46844869365d5c9138834b8"
, and I want to add "-" after every 6th character so I have b46844-869365-d5c913-8834b8
.
I tried following solotions:
$string = implode("-", str_split($string,6));
$string = wordwrap($string, 6, '-', true);
$string = chunk_split($string, 6, '-');
but they all add a "-" at the end of the result so I get:
b46844-869365-d5c913-8834b8-
any suggestions?
