Getting numeric value from last section of a URL

Hi All,

Background:
I have a mySQL/PHP Driven site, which now needs data paging. For SEO
reasons, we use URL rewriting through out the site (So far, not one
querystring value is required). The URL of my 'paged' data will be something
like this: www.asite.com/dir/subdir/page2. What I need to do, is just get
the '2' from 'page2' which I can then use in my paging routine.

Progress so far:
I am quite new to PHP, heres what I have come up with:

$theURL = "/dir/subdir/page2"; // Define the URL, juse because I am on a
test page in the root (Would normally use $_SERVER{'REQUEST_URI'} to get the
URL)
print $theURL ."<br>";

$count = count(explode("/",undo_magic_quotes($theURL))); // Store the number
of dirs
print $count ."<br>";

// Print out the last dir section (I would expect this to be 'page2' but it
is empty!)
print "|" .$arr_bits[$count-1] ."|<br>";
print str_replace("page","",$arr_bits[$count-1]); // Here I am trying to
turn 'page2' into just '2'

Obviously I was just writing out to the page to see if I was on the right
track, not much luck so far!

Any help/advice will be much appreciated,

Simon.

You never assigned the return value of explode to $arr_bits:

$arr_bits = explode("/",undo_magic_quotes($theURL));
$count = count($arr_bits); // Store the number of dirs
print $count ."<br>";

print "|" .$arr_bits[$count-1] ."|<br>";

Great, thanks!
