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

    <para>If you have <application>Berkeley DB</application> installed and 
    wish to utilize it, apply the following patch:</para>

<screen><userinput>patch -Np1 -i ../php-&php-version;-db43-1.patch</userinput></screen>

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

<screen><userinput>./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-ncurses \
            --with-readline \
            --disable-libxml &amp;&amp;
make</userinput></screen>

    <para>To test the results, issue: <command>make test</command>.</para>

    <para>Now, as the <systemitem class="username">root</systemitem> user:</para>

<screen role="root"><userinput>make install &amp;&amp;
cp -v php.ini-recommended /etc/php.ini</userinput></screen>

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

    <note>
      <para><application>PHP</application> 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/">PHP web site</ulink>
      is highly recommended, as their online docs are very good.</para>

      <para>To enable PHP support in the <application>Apache</application> 
      web server, a new LoadModule (which should be handled automatically by the

<screen><literal>LoadModule php5_module lib/apache/libphp5.so

      <para>Also, it can be useful to add an entry for
