To refresh this document, perhaps it would be worth mentioning more modern methods to serve php content under apache httpd.
Specifically, the preferred method is now fastcgi, using either of those recipes:
(mod_fastcgi, httpd 2.2)
http://wiki.apache.org/httpd/php-fastcgi
(mod_fcgid, httpd 2.2)
http://wiki.apache.org/httpd/php-fcgid
(mod_proxy_fcgi, httpd 2.4)
http://wiki.apache.org/httpd/PHP-FPM
While the legacy mod_php approach is still applicable for some older installations, the fastcgi method is much faster, and require much less RAM to operate, based on similar traffic patterns.
Thank you!
Debian GNU/Linux installation notes
This section contains notes and hints specific to installing PHP on » Debian GNU/Linux.
Avviso
Unofficial builds from third-parties are not supported here. Any bugs should be reported to the Debian team unless they can be reproduced using the latest builds from our » download area.
While the instructions for building PHP on Unix apply to Debian as well,
this manual page contains specific information for other options, such as
using either the apt or aptitude
commands. This manual page uses these two commands interchangeably.
Using APT
First, note that other related packages may be desired like
libapache-mod-php to integrate with Apache 2, and
php-pear for PEAR.
Second, before installing a package, it's wise to ensure the package list is up to date. Typically, this is done by running the command apt update.
Example #1 Debian Install Example with Apache 2
# apt install php-common libapache2-mod-php php-cli
APT will automatically install the PHP module for Apache 2 and all of its dependencies, and then activate it. Apache should be restarted in order for the changes take place. For example:
Example #2 Stopping and starting Apache once PHP is installed
# /etc/init.d/apache2 stop # /etc/init.d/apache2 start
Better control of configuration
In the last section, PHP was installed with only core modules. It's
very likely that additional modules will be desired, such as
MySQL,
cURL,
GD,
etc. These may also be installed via the apt command.
Example #3 Methods for listing additional PHP packages
# apt-cache search php # apt search php | grep -i mysql # aptitude search php
The examples will show a lot of packages including several PHP specific ones
like php-cgi, php-cli and php-dev. Determine which are needed
and install them like any other with either apt
or aptitude. And because Debian performs
dependency checks, it'll prompt for those so for example to install
MySQL and cURL:
Example #4 Install PHP with MySQL, cURL
# apt install php-mysql php-curl
APT will automatically add the appropriate lines to the
different php.ini related files like
/etc/php/7.4/php.ini,
/etc/php/7.4/conf.d/*.ini, etc. and depending on
the extension will add entries similar to extension=foo.so.
However, restarting the web server (like Apache) is required before these
changes take affect.
Common Problems
- If the PHP scripts are not parsing via the web server, then it's likely that PHP was not added to the web server's configuration file, which on Debian may be /etc/apache2/apache2.conf or similar. See the Debian manual for further details.
- If an extension was seemingly installed yet the functions are undefined, be sure that the appropriate ini file is being loaded and/or the web server was restarted after installation.
-
There are two basic commands for installing packages on Debian (and other
linux variants):
aptandaptitude. However, explaining the subtle differences between these commands goes beyond the scope of this manual.

Compiling PHP on Ubuntu boxes.
If you would like to compile PHP from source as opposed to relying on package maintainers, here's a list of packages, and commands you can run
STEP 1:
sudo apt-get install autoconf build-essential curl libtool \
libssl-dev libcurl4-openssl-dev libxml2-dev libreadline7 \
libreadline-dev libzip-dev libzip4 nginx openssl \
pkg-config zlib1g-dev
So you don't overwrite any existing PHP installs on your system, install PHP in your home directory. Create a directory for the PHP binaries to live
mkdir -p ~/bin/php7-latest/
STEP 2:
# download the latest PHP tarball, decompress it, then cd to the new directory.
STEP 3:
Configure PHP. Remove any options you don't need (like MySQL or Postgres (--with-pdo-pgsql))
./configure --prefix=$HOME/bin/php-latest \
--enable-mysqlnd \
--with-pdo-mysql \
--with-pdo-mysql=mysqlnd \
--with-pdo-pgsql=/usr/bin/pg_config \
--enable-bcmath \
--enable-fpm \
--with-fpm-user=www-data \
--with-fpm-group=www-data \
--enable-mbstring \
--enable-phpdbg \
--enable-shmop \
--enable-sockets \
--enable-sysvmsg \
--enable-sysvsem \
--enable-sysvshm \
--enable-zip \
--with-libzip=/usr/lib/x86_64-linux-gnu \
--with-zlib \
--with-curl \
--with-pear \
--with-openssl \
--enable-pcntl \
--with-readline
STEP 4:
compile the binaries by typing: make
If no errors, install by typing: make install
STEP 5:
Copy the PHP.ini file to the install directory
cp php.ini-development ~/bin/php-latest/lib/
STEP 6:
cd ~/bin/php-latest/etc;
mv php-fpm.conf.default php-fpm.conf
mv php-fpm.d/www.conf.default php-fpm.d/www.conf
STEP 7:
create symbolic links for your for your binary files
cd ~/bin
ln -s php-latest/bin/php php
ln -s php-latest/bin/php-cgi php-cgi
ln -s php-latest/bin/php-config php-config
ln -s php-latest/bin/phpize phpize
ln -s php-latest/bin/phar.phar phar
ln -s php-latest/bin/pear pear
ln -s php-latest/bin/phpdbg phpdbg
ln -s php-latest/sbin/php-fpm php-fpm
STEP 8: link your local PHP to the php command. You will need to logout then log back in for php to switch to the local version instead of the installed version
# add this to .bashrc
if [ -d "$HOME/bin" ] ; then
PATH="$HOME/bin:$PATH"
fi
STEP 9: Start PHP-FPM
sudo ~/bin/php7/sbin/php-fpm

To install LAMP stack on Ubuntu (+Server) from 10.04 you need first install taskel and then lamp-server for example:
Install taskel, follow terminal guides:
sudo apt-get install tasksel
Install LAMP stack package from Ubuntu repository:
sudo tasksel install lamp-server

With Apache2 and Php4 under Debian Sarge there is an extra configuration file : /etc/apache2/sites-available/default
This file is not clearly documented, at least not for noobs, in Apache docs.
It overrides the conf file in the way you expect the /etc/apache2/conf.d/apache2-doc to do according to the README.
Add ExecCGI to it to get rid of "Options ExecCGI is off in this directory" errors.

On Ubuntu (since 7.04), rather do:
sudo tasksel install lamp-server

On Ubuntu:
sudo apt-get install apache2 php5 mysql-client-5.0 mysql-server-5.0 phpmyadmin libapache2-mod-php5 libapache2-mod-auth-mysql php5-mysql
then restart the computer/start mysql manually
