Well, could it be as simple as using strpos() to find the <br>s? (Actually in
this case stripos() would be better because it's not case sensitive) (Warning -
NOT tested!)
if (!isset($page) || $page == "")
$page = 1;
$pos = 0;
for ($cpage = 0; $cpage < $page; $cpage++) {
$pstart = $pos;
for ($cpar = 0; $cpar < 6; $cpar++) { // Change 6 to # of paras/page
$oldpos = $pos;
$pos = stripos($text, '<br>', $pos);
if ($pos === false) // no more found
break;
else
$pos++; // Point to next char and continue
}
}
if ($oldpos > $pstart)
echo substr($text, $pstart, $oldpos);
else
echo "End of article";
Probably not perfect, but it should get you started.
Alternatively, you could split the paragraphs into an array and just count the
number of items you need, i.e. (Again no tested)
if (!isset($page) || $page == "")
$page = 1;
$tarray = preg_split('/<br>/i', $text);
$pcount = 6; // Number of paragraphs per page
$startpar = ($page-1) * $pcount;
$endpar = min($startpar + $pcount, count($tarray)); // Don't go past end
for ($i = $startpar; $i < $endpar; $i+)
echo $tarray[$i];
