PHP6 Changes, Server Migration Impacts

Server migration to PHP6 could cause a lot of headaches for countless programmers.

Major changes are coming in this new version of PHP.

When PHP 5 was released, many hosting servers decided to maintain both PHP versions (4 and 5), due to numerous scripts having stopped working after the PHP update.

In version 6, the changes are even bigger and we will certainly have hosting servers providing three versions of PHP 4, 5 and 6.

Among the changes, the one that will cause the most impact is the complete removal of register_globals. In PHP version 5, register_globals already comes disabled by default, but in version 6, there won’t even be an option to enable it, since in this new version of PHP, register_globals will not exist.

Other changes will make developers readapt to the language.
