On April 1st I already wrote about the end of life of PHP 4 - more as a joke than a real statement. It was April 1st after all. However, after a little discussion on the PHP Internals mailing list the development team actually reached consensus in quite an amazing time. So now it is official - support for PHP 4 will be dropped by the end of the year. That means there are 172 days left to convert your applications to PHP 5 - good luck!
