<title>Installation of <application><acronym>PHP</acronym></application></title>

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

<para>Install <application><acronym>PHP</acronym></application> by
running the following commands:</para>

<screen><userinput><command>./configure --prefix=/usr \
            --sysconfdir=/etc \
            --with-apxs2 \
            --with-config-file-path=/etc \
            --with-zlib \
            --with-bz2 \
            --enable-ftp \
            --with-gettext \
            --with-iconv \
            --with-ncurses \
            --with-readline \
            --disable-libxml &amp;&amp;
make &amp;&amp;
make install &amp;&amp;
cp php.ini-recommended /etc/php.ini</command></userinput></screen>

<para>Remove the <parameter>--disable-libxml</parameter> switch if you
have <xref linkend="libxml2"/> installed otherwise
<command>pear</command> will not be built.</para>

<note><para><acronym>PHP</acronym> has many more configure options that
will enable support for certain things. You can use
<command>./configure --help</command> to see a full list of the
available options. Also, use of the
<ulink url="http://www.php.net/"><acronym>PHP</acronym> web site</ulink>
is highly recommended, as their online docs are very good.</para></note>

<sect3><title>Configuration Information</title>

<para>To enable <acronym>PHP</acronym> support in the
<application>Apache</application> web server,
a new LoadModule (this one should be handled automatically by the
<command>make install</command> command) and AddType directives must be added to the
<filename>httpd.conf</filename> file:</para>

<screen><userinput>LoadModule php5_module lib/apache/libphp5.so
AddType application/x-httpd-php .php</userinput></screen>

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