IIRC, the original intent of the question was to find a PHP implementation in case no extension is available - but wasn´t there a new package recently that can take a string with C sourcecode, compile that as an extension on-the-fly (an cache it) and then you could use that extension in your PHP source? Wouldn´t that be a faster implementation (at least from the second run onwards)? At least it wouldn´t require going through the sources and convert into (slower) PHP. Just an idea, don´t know how feasible this is. Regards, Markus -- Markus Wolff <wolff@21st.de>
