Web page capturing-web page capturing with curl in php

{Code ...}

Encapsulate a function that captures web pages with curl. it can be tested locally. after it is placed on the test server, if it is accessed and executed through a browser, the HTTP status code returned by the function returns 0 in most cases, error message 'error: name lookup timed out'. if it is an idol, 200 is returned successfully. if it is directly executed on the test server using the command line, 100% is successful. The code is as follows:

Static public function curlGet ($ url, $ data = array (), $ header = array (), $ timeout = 3, $ port = 80) {$ is_ssl = substr ($ url, 0, 5) = 'https '? 1: 0; $ ch = curl_init (); if (! Empty ($ data) {$ data = is_array ($ data )? Http_build_query ($ data): $ data; $ url. = (strpos ($ url ,'? ')? '&':"? "). $ Data;} curl_setopt ($ ch, CURLOPT_URL, $ url); curl_setopt ($ ch, CURLOPT_RETURNTRANSFER, true); curl_setopt ($ ch, CURLOPT_CUSTOMREQUEST, 'Get '); curl_setopt ($ ch, CURLOPT_FOLLOWLOCATION, 1); // whether to capture the redirected page curl_setopt ($ ch, CURLOPT_CONNECTTIMEOUT, 5); curl_setopt ($ ch, CURLOPT_TIMEOUT, $ timeout ); curl_setopt ($ ch, CURLOPT_POST, 0); // curl_setopt ($ ch, CURLOPT_PORT, $ port); curl_setopt ($ ch, CURLOPT_HTTPHE ADER, $ header); curl_setopt ($ ch, CURLOPT_REFERER, $ url); // curl_setopt ($ ch, CURLOPT_USERAGENT, self: url2useragent ($ url )); if ($ is_ssl) {curl_setopt ($ ch, CURLOPT_SSL_VERIFYPEER, false); // skip the certificate check curl_setopt ($ ch, CURLOPT_SSL_VERIFYHOST, true ); // check whether the SSL encryption algorithm exists from the certificate} $ result = array (); $ result ['result'] = curl_exec ($ ch ); $ result ['http _ Code'] = curl_getinfo ($ ch, CURLINFO_HTTP_CODE); if (0! = Curl_errno ($ ch) {$ result ['error'] = "error: \ n ". curl_error ($ ch);} curl_close ($ ch); return $ result ;}

I personally feel that it has little to do with the code. I don't know what the problem is. I hope you will be grateful for your advice.

1. set the timeout value to a greater value;
2. restart the server;
3. Check If DNS is normal

Your server is exhausted
