     <function>parse_ini_file</function> loads in the
     ini file specified in <parameter>filename</parameter>,
     and returns the settings in it in an associative array.
     By setting the last <parameter>process_sections</parameter>
     parameter to &true;, you get a multidimensional array, with
     the section names and settings included. The default
     for <parameter>process_sections</parameter> is &false;
    </para>
    <note>
     <para>
      This function has nothing to do with the
      &php.ini; file. It is already processed,
      the time you run your script. This function can be used to
      read in your own application's configuration files.
     </para>
    </note>
    <note>
     <para>
      If a value in the ini file contains any non-alphanumeric
      characters it needs to be enclosed in double-quotes (").
     </para>
    </note>
    <note>
     <simpara>
      Since PHP 4.2.1 this function is also affected by <link
      linkend="ini.safe-mode">safe_mode</link> and <link
      linkend="ini.open-basedir">open_basedir</link>.
     </simpara>
    </note>
    <para>
     The structure of the ini file is similar to that of
     the &php.ini;'s.
    </para>
    <warning>
     <para>
      If the ini file you are trying to parse is malformed, PHP will exit.
     </para>
