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 libxml2-2.12.4 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 \ --without-pear \ --enable-fpm \ --with-fpm-user=apache \ --with-fpm-group=apache \ --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 18000) 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-8.3.2 && install -v -m644 CODING_STANDARDS* EXTENSIONS NEWS README* UPGRADING* \ /usr/share/doc/php-8.3.2
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-8.3.2 && gunzip -v /usr/share/doc/php-8.3.2/php_manual_en.html.gz
For the “Many HTML files” tarball:
tar -xvf ../php_manual_en.tar.gz \ -C /usr/share/doc/php-8.3.2 --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.
--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 automatically start the php-fpm daemon when the system is rebooted, install the /etc/rc.d/init.d/php
bootscript from the blfs-bootscripts-20231119 package as the root
user:
make install-php
