How to update to php 5

Last Modified: Jun 9, 2008, 4:26 pm

Note: If you want the latest version of php and apache, it's recommended you use custombuild:
http://files.directadmin.com/services/custombuild/1.1

The following guide is only to be used if if you still want to use the old apache versions... basically, only if you still need FrontPage.

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-5.2.4.tar.gz from php.net into your customapache directory:

cd /usr/local/directadmin/customapache
wget http://files.directadmin.com/services/customapache/php-5.2.4.tar.gz

2) change your build script for the new version:

nano build

change: PHP_VER=4.4.4
to: PHP_VER=5.2.4

3) build php normally:

./build clean
./build php n

If you're using apache 2.x, use

./build clean
./build php_ap2 n

instead.

4) edit /etc/httpd/conf/httpd.conf
Remove any referce of:

LoadModule php4_module modules/libphp4.so

and make sure they're replaced with:

LoadModule php5_module modules/libphp5.so

Remove any reference of:

AddModule mod_php4.c

and replace with:

AddModule mod_php5.c

5) find this piece of 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:

<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:

<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:

<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:

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:

--with-xml \

to:

--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:

yum -y install libxml2-devel libxslt-devel

FreeBSD:

pkg_add -r libxml2
pkg_add -r libxslt

On debian systems if using apt-get to install libxml2-dev and libxml2-utils doesn't work, then install from source:

wget http://files.directadmin.com/services/customapache/libxml2-2.6.30.tar.gz
tar xvzf libxml2-2.6.30.tar.gz
cd libxml2-2.6.30
./configure
make && make install

then recompile php as usual.
