Da Massive writes with this excerpt from ComputerWorld:
"For a technology that has been in stable release since May 22, 2000, PHP 4 has finally reached the end of its official life. With the release of PHP 4.4.9, official support has ended and the final security patch for the platform issued. ...With eight years of legacy code out there, it is likely that there are going to be a fairly large number of systems that will not migrate to PHP 5 in the near future, and a reasonable proportion of those that will not make the migration at all. For those who are not able to migrate their systems to the new version of PHP, noted PHP security expert Stefan Esser will continue to provide third party security patching for the PHP 4 line through his Suhosin product."
