    <simpara>
     The <function>highlight_string</function> function outputs a syntax
     highlighted version of <parameter>str</parameter> using the colors defined
     in the built-in syntax highlighter for PHP.
    </simpara>
    <simpara>
     If the second parameter <parameter>return</parameter> is set to &true;
     then <function>highlight_string</function> will return the highlighted
     code as a string instead of printing it out. If the second parameter is
     not set to &true; then <function>highlight_string</function> will
     return &true; on success, &false; on failure.
