Parse web page without save local?

Parse web page without save local?

Sorry my English a little. I am using CURL because web page is required
this function. I don't get file_get_contents of page. How to parse page
without page save? (fopen,fwrite)
<?PHP
function fileGet($url, $timeout = 55, $ref=true){
$useri = $_SERVER['HTTP_USER_AGENT'];
@set_time_limit($timeout);
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_COOKIESESSION, true);
curl_setopt($curl, CURLOPT_RETURNTRANSFER,true);
curl_setopt($curl, CURLOPT_FOLLOWLOCATION,true);
curl_setopt($curl, CURLOPT_COOKIE,
'PHPSESSID=fztitsfgsafafaq25llwafd0; path:/' );
curl_setopt($curl, CURLOPT_USERAGENT, $useri);
curl_setopt($curl, CURLOPT_ENCODING, 'gzip,deflate');
curl_setopt($curl, CURLOPT_TIMEOUT, $timeout);
curl_setopt($curl, CURLOPT_REFERER,$url);
$data = curl_exec($curl);
curl_close($curl);
// Save Page Start
$fp = fopen('data.html', 'w');
fwrite($fp, $data);
fclose($fp);
// Save Page End
return $data;
}
// Start Code
fileGet("http://www.example.com",10); // Start Function
$html = file_get_html('data.html'); // Open Saved Page In Local
foreach($html->find('div.columns') as $article) {
// Events.....
mysql_query("Insert Query");
}
// End Code
?>
