Example of getting the WIF of a BIP32 extended private key, for import using bitcoind's "importprivkey" command.

You're very close; BIP32's specification says all public keys are in compressed format, meaning that's what is hashed. To create the WIF that indicates you want to use the compressed address, put '01' at the end! That's it; the WIF this yields is the right address as per brainwallet.
BitcoinLib::private_key_to_WIF(BIP32::import($master[0])['key'].'01', '6f')."\n";

I'll add an argument to that function and mention it around the documentation to clear this up.

Now possible by specifying an argument:

bitcoin-lib-php/src/BitcoinLib.php

Line 351 in 20daa7a

public static function private_key_to_WIF($privKey, $compressed = FALSE, $address_version)
