PHP 5?

[steve]

Hi, I am finally thinking of upgrading code from 4.xx to 5.xxx.

I think I am a bit ’dated’ with my question, but here we go.

What are the pitfalls I should look for in this upgrade. Does
everything run just fine- at least code you have tried? Can you share
some experiences on this.

Re: PHP 5?

PHP 5 is at least ten times better than PHP 4. It has a lot of extra
features that make it more like a true object-oriented language. A
must-have. It is fully forward-compatible with previous versions, but not
completely backwards-compatible. This is mainly as a result of the new and
much improved object model. Some of the things that work in PHP 5 but not
PHP < 5 are:

- private/protected member variables/functions in classes
- variable size arrays in classes
- default values for function parameters passed by reference
- various functions, like stripos, str_split, etc. go here for an
_incomplete_ list: http://www.zend.com/php5/whats-new.php

Re: PHP 5?

Well, for what it's worth, I began programming in PHP two years ago
and, at this time, I read up to date manuals and documentation so that
I didn't use deprecated ways of doing things.

I've got one or two sites that are getting fairly large and made the
switch two months ago. It went OK, not a single problem.

It looks like some scripts that have some legacy instructions in them
can be buggy. But my own PHP 4.x scripts went smoothly to PHP 5. Give
it a try on another server if you can.

Thank you Jean and Peter. I will have different version environments
for a while, so it is heartening to think that they could all be
running without code modifications.

Peter, impressive list of features from Zend site.

I will just run my old code on a test server and see how it goes.

When in doubt, read the PHP manual:

If you were using OCI driver, it no longer works with PHP5.
Re-writing this was a pain.
