Installation of PHP

[Note]

Note

You can use PHP for server-side scripting, command line scripting or client-side GUI applications. The book provides instructions for setting up PHP for server-side scripting as it is the most common form.

If you have Berkeley DB installed and wish to utilize it, apply the following patch: 

patch -Np1 -i ../php-5.0.3-db43-1.patch

Install PHP by running the following commands: 

./configure --prefix=/usr \
            --sysconfdir=/etc \
            --with-apxs2 \
            --with-config-file-path=/etc \
            --with-zlib \
            --enable-bcmath \
            --with-bz2 \
            --enable-calendar \
            --enable-dba \
            --enable-exif \
            --enable-ftp \
            --with-gettext \
            --with-iconv \
            --with-ncurses \
            --with-readline \
            --disable-libxml &&
make &&
make install &&
cp php.ini-recommended /etc/php.ini

Remove the --disable-libxml switch if you have libxml2-2.6.17 installed otherwise pear will not be built.

[Note]

Note

PHP has many more configure options that will enable support for certain 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.

Configuring PHP

Config files

/etc/php.ini, /etc/pear.conf

Configuration Information

To enable PHP support in the Apache web server, a new LoadModule (this one 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

Also, it can be useful to add an entry for index.php to the DirectoryIndex directive of the httpd.conf file.

Contents

The PHP package contains pear, php, php-config, phpextdist and phpize.
