Upgrading My Blog Environment to PHP5

PHP Logo

My Japanese blog is hosted on iza!, I really need not consider its environment, but my English blog is running on the environment of my own so that I may try new experimentals.

Finally, I did upgrade the environment of English one from PHP4 to PHP5.

As you may know, support for PHP4 has been discontinued since last year, I think I must finish using this, but some technical problems occured, it was a little bit hard to solve them.

Upgrading to PHP5 has been completed, it improved totally the blog’s system perfomarnce including more rapid screen output.

Today I’m relatively free to do something, soon or later I will be able to migrate my web applications running on PHP4 as well as the blog.
