    Hi simon,

    Here is a snippet based on your example that should get you going : 

    $content="<li class='current'><B>1</B> / 381</li><a href='website'  ,i need to receive number 385 in php";


$startsAt = strpos($content, "<B>1</B> /") + strlen("<B>1</B> /");
$endsAt = strpos($content, "</li><a href='website'", $startsAt);
$result = substr($content, $startsAt, $endsAt - $startsAt);
echo $result;
    PHP:
    No regular expression there.
    Hope it helps

    Another way of doing it:

    
$a = "<li class='current'><B>1</B> / 385</li><a href='website'";
preg_match_all('/\d+/', $a, $res);
echo "Showing: {$res[0][0]} To {$res[0][1]}";
    PHP:
    Assuming they are the first two numbers in the string.
