Let's talk about the next idea. Using PHP's curl function to store cookies, google's search page cannot be opened using file_get_connents. You must simulate the browser completely. Baidu is different. You can directly use file_get_conntens to capture the page, then you can use the regular expression to process it. Baidu will not be listed here.

<? Php

Header ("Content-Type: text/html; charset = UTF-8 ");

 

Function ggsearch ($ url_s, $ keyword, $ page = 1 ){

$ EnKeyword = urlencode ($ keyword );

 

$ RsState = false;

 

$ Page_num = ($ page-1) * 10;

 

 

If ($ page <= 10 ){

$ Interface = "eth0:". rand (1, 4); // avoid gg ip Address

$ Cookie_file = dirname (_ FILE _). "/temp/google.txt"; // store cookie values

$ Url = "http://www.google.com/search? Q = $ enKeyword & hl = en & prmd = imvns & ei = jpnjtvlfi8hlggexwdpm & start = $ page_num & sa = N ";

$ Ch = curl_init ();

 

Curl_setopt ($ ch, CURLOPT_URL, $ url );

 

// Curl_setopt ($ ch, CURLOPT_USERAGENT, $ _ SERVER ['HTTP _ USER_AGENT ']); // obtain the browser type

Curl_setopt ($ ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv: 1.9.1.2) Gecko/20090729 Firefox/3.5.2 GTB5 ");

Curl_setopt ($ ch, CURLOPT_INTERFACE, "$ interface"); // specify the access IP Address

Curl_setopt ($ ch, CURLOPT_RETURNTRANSFER, 1 );

 

Curl_setopt ($ ch, CURLOPT_FOLLOWLOCATION, 1 );

 

Curl_setopt ($ ch, CURLOPT_COOKIEJAR, $ cookie_file );
