How can I optimize this curl script? (PHP) [on hold]

When I run var_dump($title), I get results really quick, but my script fetchs the whole page in order to get one result, then do it again, again. How can I do this job faster and optimize my code?

The following script works but it needs to be optimized because it works very slowly.

for ($j = 1; $j <= 1; $j++) { // number of pages I want to fetch, i.e., 1
    for ($i = 0; $i < 5; $i++) { // every page contains 20 records
        $site = "http://www.example.com/index.php?route=product/category&path=5_6&page=$j";         
        $ch = curl_init();
        $hc = "YahooSeeker-Testing/v3.9 (compatible; Mozilla 4.0; MSIE 5.5; Yahoo! Search - Web Search)";
        curl_setopt($ch, CURLOPT_REFERER, 'http://www.google.com');
        curl_setopt($ch, CURLOPT_URL, $site);
        curl_setopt($ch, CURLOPT_USERAGENT, $hc);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        $site = curl_exec($ch);
        curl_close($ch);
        preg_match_all('@><a itemprop="url" href="http://www.example.com/id/(.*?)/(.*?).html&path=(.*?)"><span itemprop="name">(.*?)</span></a>@', $site, $title);

        $title[3][$i] = strip_tags($title[3][$i]); // strip tags
        $title[3][$i] = preg_replace('~.*?>~', '', $title[3][$i]);
        echo $title[3][$i]."<br>";
    }
}
