PHP4 End of Life

Got to hand it to the internals people, when an idea’s a good one, they run with it. First the announcement that namespaces are now officially a part of the development trunk for PHP, then this:

PHP 4 end of life announcement
[13-Jul-2007]

Today it is exactly three years ago since PHP 5 has been released. In those three years it has seen many improvements over PHP 4. PHP 5 is fast, stable & production-ready and as PHP 6 is on the way, PHP 4 will be discontinued.

The PHP development team hereby announces that support for PHP 4 will continue until the end of this year only. After 2007-12-31 there will be no more releases of PHP 4.4. We will continue to make critical security fixes available on a case-by-case basis until 2008-08-08. Please use the rest of this year to make your application suitable to run on PHP 5.

For documentation on migration for PHP 4 to PHP 5, we would like to point you to our migration guide. There is additional information available in the PHP 5.0 to PHP 5.1 and PHP 5.1 to PHP 5.2 migration guides as well.

So we will finally see adoption rates for PHP5 climb a bit. You have to wonder – will the lessons learnt here prevent the PHP4-5 problems during the PHP5-6 cycle?
