<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>
|
|
|
|
<note>
|
|
<para><application>PHP</application> has many more
|
|
<command>configure</command> 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>
|

</note>
|

<para>Remove the <parameter>--disable-libxml</parameter> switch if you
|

have <xref linkend="libxml2"/> installed otherwise

<command>pear</command> will not be built.</para>
|
|

<para>Install <application>PHP</application> by

running the following commands:</para>

search utility of your browser. If you downloaded any of the documentation,

the instructions below can be issued by the

these instructions assume English docs, modify the tarball names below if

necessary).</para>
