Online graph in website

[rrn rose]

hi all ,

in my website there is a graph showing some values . that graph is taken from some other site named www.xxxx.com

graph is displayed . but the problem is that. whenever the graph changes in the www.xxxx.com , the change should also reflect in my website.

change is reflected but only after 3 , 4 hours after the graph changes in www.xxxx.com.

the change should be reflected at once , how is it possible?
below shown is the code for updating the graph
[PHP]
<? php
$ch = curl_init("http://www.xxxx.com");
$fp = fopen("location where it is saved", "w");

curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);

curl_exec($ch);
curl_close($ch);
fclose($fp);
?>[/PHP]


please give a solution..thanks...

Once you retrieve the data what are you doing with it ? can you post that portion of PHP too ?
