$limit = $offset.', '.$results_per_page;

$navigation = '';
$min = 1;
$max = 0;
while ($min < $property_count) {
  if ($min > 1) {
    $navigation .= ' | ';
  }
  $max = $min + $results_per_page - 1;
  if ($max > $property_count) {
    $max = $property_count;
  }
  if (($min - 1) == $offset) {
    $navigation .= '<b>'.$min.'-'.$max.'</b>';
  } else {
    $navigation .= '<a href="'.$PHP_SELF.'?reference='.$reference.'&location='.$location.'&size='.$size.'&offset='.($min - 1).'">'.$min.'-'.$max.'</a>';

Goto php.net and read the PHP manual.

Does 'full stop' in the UK translate to "period" for us Yanks?

The period/full stop is the 'concatenation operator'.

So, yes, in line 1 you are creating a new variable from the variable $offset, the string literal ', ' (space, comma (at least that what we call them over here 🙂 )) and the variable $results per page. Similar usage in the 2nd area you mention.

Yeah, reading the manual's a good idea.

HTH, 🙂
