PHP-5.5.9

Introduction to PHP

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.

This package is known to build and work properly using an LFS-7.5 platform.

Installation of PHP

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.

[Note]

Note

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/svn/php_configure.txt.

If, for whatever reason, you don't have libxml2-2.9.1 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:

patch -Np1 -i ../php-5.5.9-libmagic_fix-1.patch &&
sed -i -e 's/2.6.5 2.7/& 3.0/' configure &&
./configure --prefix=/usr                \
            --sysconfdir=/etc            \
            --mandir=/usr/share/man      \
            --with-apxs2                 \
            --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            \
            --with-readline              &&
make

To test the results, issue: make test. A few tests may fail.

Now, as the root user:

make install                                         &&
install -v -m644 php.ini-production /etc/php.ini     &&

install -v -m755 -d /usr/share/doc/php-5.5.9 &&
install -v -m644    CODING_STANDARDS EXTENSIONS INSTALL NEWS README* UPGRADING* php.gif \
                    /usr/share/doc/php-5.5.9 &&
ln -v -sfn          /usr/lib/php/doc/Archive_Tar/docs/Archive_Tar.txt \
                    /usr/share/doc/php-5.5.9 &&
ln -v -sfn          /usr/lib/php/doc/Structures_Graph/docs \
                    /usr/share/doc/php-5.5.9

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-5.5.9 &&
gunzip -v /usr/share/doc/php-5.5.9/php_manual_en.html.gz

For the “Many HTML files” tarball:

tar -xvf ../php_manual_en.tar.gz \
    -C /usr/share/doc/php-5.5.9 --no-same-owner

Command Explanations

sed -i -e 's/2.6.5 2.7/& 3.0/' configure: Make configure accept the version 3.0 of Bison as a valid version.

--with-apxs2: This parameter builds the Apache HTTPD 2.0 module.

--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.

Configuring PHP

Config Files

/etc/php.ini and /etc/pear.conf

Configuration Information

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.

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 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 httpd.conf file:

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 the httpd.conf file. Lastly, adding a line to setup 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.
