    <question>
     <para>Where can I obtain PHP?</para>
    </question>
    <answer>
     <para>
      You can download PHP from any of the members of the
      PHP network of sites. These can be found at 
      <ulink url="&faqurl.php;">&faqurl.php;</ulink>.
      You can also use anonymous CVS to get the absolute latest
      version of the source. For more information, go to 
      <ulink url="&faqurl.php.cvs;">&faqurl.php.cvs;</ulink>.

   <qandaentry id="faq.obtaining.precompiled">
    <question>
     <para>Are pre-compiled binary versions available?</para>
    </question>
    <answer>
     <para>
      We only distribute precompiled binaries for Windows systems,
      as we are not able to compile PHP for every major Linux/Unix
      platform with every extension combination. Also note, that
      many Linux distributions come with PHP built in these days.
      Windows binaries can be downloaded from our <ulink
      url="&faqurl.php.download;">Downloads</ulink> page, for Linux
      binaries, please visit your distributions website.

   <qandaentry id="faq.obtaining.optional">
    <question>
     <para>
      Where can I get libraries needed to compile some of
      the optional PHP extensions?

    </question>
    <answer>
     <para>
      <note>
       <simpara>
        Those marked with * are not thread-safe libraries, and
        should not be used with PHP as a server module in the multi-threaded
        Windows web servers (IIS, Netscape). This does not matter in Unix
        environments, yet.

    <question>
     <para>How do I get these libraries to work?</para>
    </question>
    <answer>
     <para>
      You will need to follow instructions provided with the library. Some of
      these libraries are detected automatically when you run the 'configure'
      script of PHP (such as the GD library), and others you will have to
      enable using '<literal>--with-EXTENSION</literal>' options to 
      '<literal>configure</literal>'. Run 
      '<literal>configure --help</literal>' for a listing of these.

    <question>
     <para>
      I got the latest version of the PHP source code from the CVS
      repository on my Windows machine, what do I need to compile it?
     </para>
    </question>
    <answer>
     <para>
      First, you will need Microsoft Visual C++ v6 (v5 may do
      it also, but we do it with v6), and you will need some
      support files. See the manual section about
      <link linkend="install.windows.build">building PHP from
      source on Windows</link>.
