PHP is the PHP Hypertext Preprocessor. Primarily used in dynamic web sites, it allows for programming code to be directly embedded into the HTML markup.

You can use PHP for server-side scripting, command-line scripting or client-side GUI applications. This book provides instructions for setting up PHP for server-side scripting as it is the most common form.
PHP has many more configure options that will enable support for various things. You can use ./configure --help to see a full list of the available options. Also, use of the PHP web site is highly recommended, as their online docs are very good. An example of a configure command that utilizes many of the most common dependencies can be found at http://anduin.linuxfromscratch.org/files/BLFS/6.3/php_configure.txt.
If, for whatever reason, you don't have libxml2-2.6.31
installed, you need to add
--disable-libxml to the configure command in the
instructions below. Note that this will prevent the pear command from being built.
Install PHP by running the following commands:
sed -i 's/const char \*errpfx,/const DB_ENV *dbenv, & const/' \ ext/dba/dba_db4.c && ./configure --prefix=/usr \ --sysconfdir=/etc \ --with-apxs2 \ --enable-force-cgi-redirect \ --enable-discard-path \ --with-config-file-path=/etc \ --with-zlib \ --enable-bcmath \ --with-bz2 \ --enable-calendar \ --enable-dba \ --enable-exif \ --enable-ftp \ --with-gettext \ --enable-mbstring \ --with-ncurses \ --with-readline && make
To test the results, issue: make test. Some of the tests are known to fail.
Now, as the

The pre-built HTML documentation is packaged in two forms: a
tarball containing many individual files, useful for quick loading
into your browser, and one large individual file, which is useful
for using the search utility of your browser. If you downloaded
either, or both, of the documentation files, issue the following
commands as the
root user to
install them (note these instructions assume English docs, modify
the tarball names below if necessary).
For the “Single HTML” file:
install -v -m644 ../php_manual_en.html.gz \ /usr/share/doc/php-5.2.3 && gunzip -v /usr/share/doc/php-5.2.3/php_manual_en.html.gz
For the “Many HTML files” tarball:
tar -xvf ../php_manual_en.tar.gz -C /usr/share/doc/php-5.2.3 && chown -v -R root:root /usr/share/doc/php-5.2.3/html

The file used as the default

by the PHP development team.
This file modifies the default behavior of PHP. If no
/etc/php.ini is used, all configuration
settings fall to the defaults. You should review the comments in
this file and ensure the changes are acceptable in your
You may have noticed the following from the output of the make install command:
You may want to add: /usr/lib/php to your php.ini include_path
If desired, add the entry using the following command as the
sed -i 's@php/includes"@&\ninclude_path = ".:/usr/lib/php"@' \ /etc/php.ini
To enable PHP support in the Apache web server, a new LoadModule (which
should be handled automatically by the make install command) and
AddType directives must be added to the
LoadModule php5_module lib/apache/libphp5.so AddType application/x-httpd-php .php
Additionally, it can be useful to add an entry for
index.php to the DirectoryIndex directive of
httpd.conf file. Lastly, adding
a line to setup the

may be desirable:
AddType application/x-httpd-php-source .phps
