[gentoo-server] php 4 to 5

[gentoo-server] php 4 to 5

[Ben Munat]

Hello list,

So, I know I'm a bad gentoo administrator and all, but I am just getting around 
to moving from php 4 to 5. Was wondering if anyone knew of any gotchas to watch 
out for or guides to help with the process. Everything I'm finding through 
google seems to be about the update from the old php packages to dev-lang/php, 
which I did a long time ago.

It would be really sweet if I could just unmask php and emerge. What are the 
chances of it being that easy?

Thanks,

Ben

I would say the chances are 50/50 :)  It really depends on what is being 
used.  If you have a lot of complex applications, that use a lot of PEAR 
or other PHP packages it might take a few goes to get all the packages 
you need for php5.  Also if you have a lot of applications that still 
are not compatible with PHP 5 (which is my case I believe, still need to 
find time to go and check it), you will run into problems.

I've read somewhere about people moving to php5 will run php4 through 
cgi, and then just process the document extensions differently. (a 
simple bash script could go through several sub direcotries renaming all 
.php to .php4).  Just some thoughts.

I'd ask you keep us , and specifically me , updated on how well the 
process goes :D

It depends on the php scripts you use.
If they are php5 compatible, the migration should be smooth.
php-dependant libraries need to be re-emerged, same goes for pecl packages 
(pecl4 -> pecl5).

If you've got scripts which are php5 incompatible, you have a problem.
One solution is to run php4 as cgi for that specific docroot, or have both 
php4 and php5 running as modules using the concurrent patch (but I wouldn't 
advise that as it *sadly* isn't supported upstream).


I just wish they would make it easier for running different php versions on 
the same server, as apache modules....and now with php6 being 
released "soon".... but oh well ;-)


Hope this helped.

Thanks to both Georges and Ryan for their replies. Yeah, I suppose it would have 
made sense for me to mention what I'm using.

I have phppgadmin, phpmyadmin, squirrelmail, and postfixadmin (in an overlay, 
and unfortunately with some customization) on my machine. I think at least the 
first three are php5-ready.

For custom stuff, there is one complete site -- written by my brother -- using 
php. Hopefully it's not using any php4-specific stuff. I think he does use some 
PEAR modules... MDB2, Http_Client, etc. Luckily I think that site's going to 
reach end-of-life soon (was an internal site for a research project), so maybe 
this update will rush that along. :-)

Other than this, there are a few pages here and there that use some php. I don't 
think any of those use any libraries or fancy stuff... hopefully not.

Now, I should not need to re-emerge the webapps (phpmyadmin, etc.), right? They 
don't have any compiled code. I'd rather not deal with the configs if possible. 
I will re-emerge all the PEAR/PECL stuff though.

Will write again to let you know how it went.

Ben

PS: Hmm, so the email the other day said that php4 would be removed from the 
tree yesterday. So, I suppose that this means that if I move to php5 there's no 
way to move back to php4? :-o

I "think" postfixadmin is compatible.
phpmyadmin is, phppgadmin not sure, and squirrel dunno either....but a quick 
check on the respective websites will tell :-).

If you got scripts using PEAR modules, they don't necessarily brake, it's 
rather more fancy scripts in general which brake :-).

Nope...only pecl + php itself

I guess as you don't have that much scripts, checking the site for the above 
mentioned tools and testing with the other custom stuff should do the job.
You shouldn't hit too much trouble I guess.


Goo luck :-)

I've run all four in PHP 5. You should have no problems.

I have a similar problem but minor compared to what some will be having on
large sites. I have a server with both 4 and 5 but mostly 4 codebase.
There's about a dozen virtual hosts that need to be got\ten up to speed.

My appraoch is is to build a second server on an old box, mirroring
everything in the web root but with only php5 running and that way I'll see
what will break before doing the real thing.

Well, my move from php4 to php5 was pretty anti-climactic. I just unmasked php 
and emerged. Had to switch to php5 with php-select after that. Then I checked my 
sites and I haven't found any problems so far.

Well, there was an error in phpmyadmin that was due to a config issue, but that 
may have been there for a while... I didn't have my config.inc.php set up right.

So, if you don't have a lot of custom php, this move should be a snap. 
(Hopefully I haven't just missed subtle problems.)

Good to hear, thanks for the update :)
