What happens if you try running:
sudo apt-get update && sudo apt-get upgrade && sudo apt-get dist-upgradeThat should update it. Checking my Ubuntu install, PHP5 is in a seperate package to version four, so if you want to install it run:
sudo apt-get install php5a Padded Cell our articles site!

So if i install php 5 as above it wont change anything with my current setup with php4 - meaning my websites will be ok and all configuration?
To use php 5 i should just change apache config to point to php 5 rather than php4?

If you run the update commands, your config files won't change. You will risk broken sites if you upgrade to PHP 5. That's why many hosts are lazy to do it.
I would back up all the config files and then upgrade to PHP5. You may have some downtime reconfiguring some things, but PHP4 is no longer supported and if your version is out of date, you are running a security risk which could result in unplanned downtime.

How does PHP5 differ from PHP4?

Well, I had a nasty surprise with an email validation script I wrote and tested on PHP5 but client's server was running PHP4
PHP4 does not support the strpbrk() function, eg
$invalidChar = strpbrk($fromEmail, '!#$%^&*()_+=-{}|\]["\':;?/><,');- I had to replace this one line with a whole list of$invalidChar .= strpos($fromEmail, "!");statementsAnother place I just did the validation with JavaScript...
When I asked, the server admin said "PHP5 is not stable" I think that is BS, I have had no problems with PHP5
However I have another client whose WebScribble WebDate platform just stopped working suddenly. Been around the bush several times with fresh installs etc. I see they are running PHP 5.25 but they won't give me a straight answer about when it began. My hunch is that is the cause, or maybe a MySQL misconfiguration. The script connects with the db on install to create all the tables, but in use it does not connect....

Does this help? "Migrating legacy PHP 4 applications to PHP 5"

The problem was actually migrating a PHP5 script to PHP4
- no strpbrk() in PHP4 -
As for the web hosting problem, I have had Paul, who runs an independent Webscribble WebDate forum, look it over and he's scratching his head. Next stop is changing the DNS (app is licensed to a specific domain) and trying out on my server for proof it works.
