Despite the manual claiming that this is available in PHP 5.5 and above, this function wasn't made available in my local install.

I expect that having a prehistoric OpenSSL library version installed is the likely culprit.

If you're using PHP 5.5 and don't have this function available in your OpenSSL extension, look at the functionally equivalent hash_pbkdf2 function instead.
