After a roller coaster career, my first php extension has hit php cvs, with all the memory leaks settled, nearly all the features done and all promises kept. Hidef, as it was originally known acquires a new and improved slogan "Constants for real" as well as a place in the PECL packages. If you want to install the module, just run this simple command and have the binary built & dropped into your php install - except for the extension=hidef.so line.
bash# pecl install "channel://pecl.php.net/hidef-0.1.0"
If this actually makes a significant difference in your code's performance, I'd say that you've done a wonderful job otherwise. Most of the code is stolen off a template Rasmus had and packaging was thanks to Pierre ... which leaves me with a distinct feeling of having put a few legos together - but to my credit, at least the peices fit.--
