In a new post to his blog today, Pierre-Alain Joye talks about a feature of the latest release of his htscanner PECL extension - the full support of PHP4.
The first releases of the new 0.8.x have published earlier this week (0.8.1 is the latest). The main change is the full support of PHP4. I will support it as long as PHP.net maintains it. The ability to keep htscanner loaded while using PHP CLI is now possible without having to tweak the configuration (useful if you use a single php.ini for both cli and cgi).
You can find out more about the htscanner extension on its PECL homepage and more about the sponsor helping Pierre make this support possible - widexs.nl
