GE Lookup Script

[Mercifull]

Does anyone have some code (or if somone else has done it, a link) to simply lookup the market price of an item on the Grand exchange in the following format:

 

 

 

www.blah.com/ge.php?id=100

 

 

 

and it just returns the figure.

 

 

 

Cheers.

 

 

 

Do not want anything fancy.

<?php



$id = $_GET['obj'];



$url = "http://itemdb-rs.runescape.com/viewitem.ws?obj=".$id;



function rs_getprices($url) {

$price = array();



$fh = fopen($url, "rb");

while (!feof($fh)) {

$line = fgets($fh);

if(!$min)

sscanf($line, "Minimum price: %s", $min);

else if(!$mar)

sscanf($line, "Market price: %s", $mar);

else if(!$max)

sscanf($line, "Maximum price: %s", $max);

else break;

}

fclose($fh);

$price['minimum'] = $min;

$price['market'] = $mar;

$price['maximum'] = $max;

return $price;

}

$item = rs_getprices($url);



?>



<?php



echo $item['market'];



?>

 

 

 

that works but its not sanitised and anyone can put obj=blahblah.com at the end instead of only allowing numbers.

 

 

 

Could someone here help me make it so it will only accept numbers and display error messages accordingly etc.?
