If your site is built with an older version of php, it may continue to work the same way as long as you aren’t using any code that’s no longer supported or anything that’s blocked for being unsafe.

Also when servers get upgraded they may or may not support old versions of php. It’s up to the hosting.

Most decent packaged software usually gets upgraded to newer versions of php in time for such a migration, so often you can just upgrade your package and you’ll be OK.
But if your software is written in say php 4 and no upgrade is available, you’ll probably run into problems by the time php 6 becomes the standard. If it worked OK with php 5 you may be safe enough. It all depends on what kind of functions you are using..
The PHP versions currently supported are: PHP 4.4 PHP 5.0, PHP 5.1, PHP 5.2, PHP 5.3 and a special additionally secured version of PHP 5.2 with Suhosin patch.
