Some parameter settings for PHP curl for collection

    Public Function Geturl ($url) {                $ip = "{rand (1, 255)}.{ RAND (1, 255)}. {rand (1, 255)}. {rand (1, 255)} ";                Initializes a CURL object        $curl = Curl_init ();        curl_setopt ($curl, Curlopt_useragent, "mozilla/5.0 (Windows NT 6.1) applewebkit/536.11 (khtml, like Gecko) chrome/$ip SAF ari/536.11 ");        curl_setopt ($curl, Curlopt_httpheader, Array ("X-forwarded-for: $ip", ' Client-ip: '. $ip. '));        curl_setopt ($curl, Curlopt_referer, "127.0.0.1");        Set the URL you need to crawl        curl_setopt ($curl, Curlopt_url, $url);        Set HEADER        curl_setopt ($curl, Curlopt_header, 1);        Sets the curl parameter, which requires the result to be saved to a string or output to the screen.        curl_setopt ($curl, Curlopt_returntransfer, 1);        Run Curl, request page        $data = curl_exec ($curl);        Close URL request        curl_close ($curl);        return $data;    }

The above settings can prevent the normal anti-collection function, the effect is quite obvious
