if/elseif dilemna

[kycan]

Here's my problem. I'm making a custom article submission script that outputs a certain article/page of article based upon the URL.

Like this:

http://www.zikes.com/articles/dawncheese/page3

It would output article "dawncheese" and page 3 of that article. My problem is this. The entire body of the article is put into one variable ($body) and inside $body, a user puts [page] to indicate a new page. On my output code, it breaks apart $body by the [page] break.

So I want my script to output the correct $page_array "piece" (created by breaking apart $body) by taking the URL and finding what page the viewer is on.

The problem is this. The only way I know how to do this is by comparing the URL to every possible possibility for the page. Like this:

if($url_specific=='page1')
{
$body = $page_array[0];
}
elseif($url_specific=='page2')
{
$body = $page_array[1];
}

Etc... because some articles could have many pages, I don't want to create a huge list of if/elseif statements to cover all possibilities.

Is there a better way of doing this??????

switch()

Sure, just extract the page number from the end of the variable:

if (eregi("^{page([0-9]+)$",} $url_specific, $matches))
   {
   $pageno = $matches[1] - 1; // convert to zero offset!
   if ($pageno < 0 || pageno >= sizeof($page_array))
      fubar();
   else
      $body = $page_array[$pageno];
   }
else
   {
   // whatever you do if $url_specific isn't set or doesn't
   // contain "PAGEnn"
   }
