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. It is also useful as a general purpose scripting language.
Development versions of BLFS may not build or run some packages properly if LFS or dependencies have been updated since the most recent stable versions of the books.

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 https://anduin.linuxfromscratch.org/BLFS/files/php_configure.txt.
If, for whatever reason, you don't have libxml2-2.13.5
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:
./configure --prefix=/usr \ --sysconfdir=/etc \ --localstatedir=/var \ --datadir=/usr/share/php \ --mandir=/usr/share/man \ --enable-fpm \ --without-pear \ --with-fpm-user=apache \ --with-fpm-group=apache \ --with-fpm-systemd \ --with-config-file-path=/etc \ --with-zlib \ --enable-bcmath \ --with-bz2 \ --enable-calendar \ --enable-dba=shared \ --with-gdbm \ --with-gmp \ --enable-ftp \ --with-gettext \ --enable-mbstring \ --disable-mbregex \ --with-readline && make
To test the results, issue: make test. Several tests (out of over 20000) may fail, in which case you are asked whether you want to send the report to the PHP developers. If you want to automate the test, you may prefix the command with yes "n" | .
Now, as the root
user:
make install && install -v -m644 php.ini-production /etc/php.ini && install -v -m755 -d /usr/share/doc/php-8.4.1 && install -v -m644 CODING_STANDARDS* EXTENSIONS NEWS README* UPGRADING* \ /usr/share/doc/php-8.4.1
The default configuration files for the fastCGI process manager are
installed only if they do not already exist on the system. If this
is the first installation, they should be renamed, as the
root
user:
if [ -f /etc/php-fpm.conf.default ]; then mv -v /etc/php-fpm.conf{.default,} && mv -v /etc/php-fpm.d/www.conf{.default,} fi
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-8.4.1 && gunzip -v /usr/share/doc/php-8.4.1/php_manual_en.html.gz
For the “Many HTML files” tarball:
tar -xvf ../php_manual_en.tar.gz \ -C /usr/share/doc/php-8.4.1 --no-same-owner
The bundled pear is not installed because of a bug which might pollute the filesystem with several hidden files and directories. If pear is needed, execute the following commands to install it:
wget https://pear.php.net/go-pear.phar php ./go-pear.phar
--datadir=/usr/share/php
:
This works around a bug in the build machinery, which installs some
data to a wrong location.
--enable-fpm
: This
parameter allows building the fastCGI Process Manager.
--with-fpm-systemd
: This
parameter allows the FastCGI Process Manager to integrate with
systemd.
--without-pear
: This switch
disables installation of bundled pear software.
--with-config-file-path=/etc
: This
parameter makes PHP look for the
php.ini
configuration file in
/etc
.
--with-zlib
: This parameter
adds support for Zlib compression.
--enable-bcmath
: Enables
bc style precision
math functions.
--with-bz2
: Adds support
for Bzip2 compression functions.
--enable-calendar
: This
parameter provides support for calendar conversion.
--enable-dba=shared
: This
parameter enables support for database (dbm-style) abstraction
layer functions.
--enable-ftp
: This
parameter enables FTP functions.
--with-gettext
: Enables
functions that use Gettext text
translation.
--enable-mbstring
: This
parameter enables multibyte string support.
--with-readline
: This
parameter enables command line Readline support.
--disable-libxml
: This option allows
building PHP without libxml2
installed.
--with-apxs2
: Instead of building the
fastCGI process manager, it is possible to build an apache module. This has some performance
penalty for heavy loaded servers, but may be easier to set up. This
switch is incompatible with the --enable-fpm
and --with-fpm-...
switches.
--with-mysqli=shared
: This option
includes MySQLi support.
--with-mysql-sock=/run/mysqld/mysqld.sock
: Location
of the MySQL unix socket pointer.
--with-pdo-mysql=shared
: This option
includes PDO: MySQL support.
--with-tidy=shared
: This option
includes tidy library support.
The file used as the default /etc/php.ini
configuration file is recommended
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
particular environment.
The fastCGI process manager uses the configuration file
/etc/php-fpm.conf
. The default file
shipped with PHP includes all the /etc/php-fpm.d/*.conf
in turn. There is a
shipped /etc/php-fpm.d/www.conf
file, that contains the parameters related to the interaction
with the Apache Web server.
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
root
user:
sed -i 's@php/includes"@&\ninclude_path = ".:/usr/lib/php"@' \ /etc/php.ini
To enable fastCGI support in the Apache web server, two LoadModule directives
must be added to the httpd.conf
file. They are commented out, so just issue the following command
as root
user:
sed -i -e '/proxy_module/s/^#//' \ -e '/proxy_fcgi_module/s/^#//' \ /etc/httpd/httpd.conf
Those modules accept various ProxyPass directives. One
possibility is (as the root
user):
echo \ 'ProxyPassMatch ^/(.*\.php)$ fcgi://127.0.0.1:9000/srv/www/$1' >> \ /etc/httpd/httpd.conf
Additionally, it may be useful to add an entry for index.php
to the DirectoryIndex directive of
the httpd.conf
file. Lastly, adding
a line to set up the .phps
extension to show highlighted PHP source may be desirable:
AddType application/x-httpd-php-source .phps
You'll need to restart the Apache web server after making any
modifications to the httpd.conf
file.
To start the php-fpm daemon at boot, install
the systemd unit from the blfs-systemd-units-20240916 package by
running the following command as the root
user:
make install-php-fpm
