[RESOLVED] Getting a sentence from a site?

I want to know how would I get a number from a sentence using file_get_contents and split? This is the code I'm using...

Code:

---

<?php

$rs = file_get_contents("http://www.runescape.com/title.ws");

list($rs) = split('There are currently', $rs);
echo "$rs";

?>

---

The sentence on the website is:-

There are currently random number people playing!

When I run the code it shows me the site and stops where the sentence is and just shows the letters "There" whats wrong with the code?

PHP Code:

---

<?php

$rs = file_get_contents("http://www.runescape.com/title.ws");

$pos = strpos($rs, 'There are currently');
$number = substr($rs, $pos + 20, 50);
$pos = strpos($number, ' people playing');
$number = substr_replace($number, '', $pos);

echo $number; //$number is the number...

?>

Thanks :)
