No, I will not need to change my code.  I
am using an array as a replacement for a
database.  Here is a snippet of my file
faqData.php to give you the idea:

//  Set data to identify Web page, and set prev and next anchors
//  Note that the first set must have index explicitly set to [1]
     $tempIndex = 1;
     $dataHref[$tempIndex] = "Ambisonic/faq_section01.html";
     $dataAnchorText[$tempIndex] = "1. Where can I get this FAQ?";
     $dataCompleteText[$tempIndex] = "1. <a href=\"#SECTION1\">Where can 
I get this FAQ?</a>";
     $dataSplitText[$tempIndex] = "1. <a rel=\"section\" 
href=\"$dataHref[$tempIndex]\">Where can I get this FAQ?</a>";

     $tempIndex++;
     $dataHref[$tempIndex] = "Ambisonic/faq_section02.html";
     $dataAnchorText[$tempIndex] = "2. Corrections to the FAQ";
     $dataCompleteText[$tempIndex] = "2. <a 
href=\"#SECTION2\">Corrections to the FAQ</a>";
     $dataSplitText[$tempIndex] = "2. <a rel=\"section\" 
href=\"$dataHref[$tempIndex]\">Corrections to the FAQ</a>";
