?>
ok now when i tries this script on same page :
<?php
$page = cuload('http://www.google.com');
?>
But now without echoing the $page variable it echo the content . i donot need to echo anything here is just need to find some link from the $page variable content .. after exploring the script deeply i find that may be there was a problem in curl_exec cause if i remove the return $response still is shows the content ! i cant understand why it giving output of $page when i am not echoing $page .
please help me !

Instead of
foreach($default_options as $opt=>$value) {
if(!isset($default_options[$opt])) {$got[$opt] = $value; }
}
try this:
foreach($default_options as $opt=>$value) {
if(!empty($default_options[$opt])) {$got[$opt] = $value;}
}
