Upgrading to PHP 5.x?

So, with many scripts stopping their support for PHP 4.x, it has been announced that PHP 4.x will no longer be supported after this year. The end of life announcement can be found at:

http://www.php.net/

So my question is this...

Is there an easy way to update my VPS with DA to PHP 5.x?

What do I stand to loose/break?

Heres how to do it:
https://support.knownhost.com/index.php?_m=knowledgebase&_a=viewarticle&kbarticleid=75


Most things should work the same but certain functions may perform different. There is probably a list of functions which have been changed somewhere. The good thing about PHP i think is the errors are very helpful, so if something is no longer working, it will likely tell you.
Unfortuneately, that is is for cPanel/WHM.

I'm using DirectAdmin (DA).

Does KnownHost have a howto for that one? I haven't been able to find it yet.
 
To update to php5, the build script will still work. All that you need to do is swap out the version, compile normally and make a few modifications to your /etc/httpd/conf/httpd.conf file.

1) download the php-5.2.2.tar.gz from php.net into your customapache directory:
Code:
cd /usr/local/directadmin/customapache
wget http://files.directadmin.com/services/customapache/php-5.2.2.tar.gz
2) change your build script for the new version:
Code:
nano build
change: PHP_VER=4.4.4
to: PHP_VER=5.2.2

3) build php normally:
Code:
./build clean
./build php n
If you're using apache 2.x, use
Code:
./build clean
./build php_ap2 n
instead.

4) edit /etc/httpd/conf/httpd.conf
Remove any referce of:
Code:
LoadModule php4_module        modules/libphp4.so
and make sure they're replaced with:
Code:
LoadModule php5_module        modules/libphp5.so
Remove any reference of:
Code:
AddModule mod_php4.c
and replace with:
Code:
AddModule mod_php5.c
5) find this piece of code:
Code:
<IfModule mod_dir.c>
    DirectoryIndex index.html index.htm index.shtml index.php index.php4 index.php3 index.phtml index.cgi
</IfModule>
replace with:
Code:
<IfModule mod_dir.c>
    DirectoryIndex index.html index.htm index.shtml index.php index.php4 index.php5 index.php3 index.phtml index.cgi
</IfModule>
Find this:
Code:
<IfModule mod_php4.c>
        AddType application/x-httpd-php .inc .php .php4 .php3 .phtml
        AddType application/x-httpd-php-source .phps
    </IfModule>
(it might have AddHandler instead of AddType)
replace with:
Code:
<IfModule mod_php5.c>
        AddHandler application/x-httpd-php .inc .php .php5 .php4 .php3 .phtml
        AddHandler application/x-httpd-php-source .phps
    </IfModule>
Then restart apache.

If you get the following error while compiling php:
Code:
 checking whether to enable LIBXML support... yes
checking libxml2 install dir... no
checking for xml2-config path...
configure: error: xml2-config not found. Please check your libxml2
installation.

*** There was an error while trying to configure php. Check the configure.php file
Then edit the configure.php file (or configure.php_ap2 if you're using apache 2), and change:
Code:
--with-xml \
to:
Code:
        --disable-libxml \
        --disable-dom \
        --disable-xml \
        --disable-simplexml \
        --disable-xmlreader \
        --disable-xmlwriter \
or else install the missing rpms/packages for xml. (libxml2-dev and libxml2-utils on debian). Redhats:
Code:
yum -y install libxml2-devel libxslt-devel
FreeBSD:
Code:
pkg_add -r libxml2
pkg_add -r libxslt

It appears that this has worked.

I'm getting an error now that my version of Zend is not supported, so I have to figure that one out now.
 
To install Zend Optimizer:
1. Login to your server via SSH
2. Run: /scripts/installzendopt
3. Follow the instructions on the screen to install Zend Optimizer



This should work :]

I actually used the DA instructions I found and it is working fine:

Code:
 cd /usr/local/directadmin/customapache
./build clean
./build update
./build zend
