Curl implements get to submit data

The code is as follows:

// Initialize a cURL object $ Curl = curl_init (); // Set the URL you want to capture Curl_setopt ($ curl, CURLOPT_URL, 'http: // www. bKjia. c0m '); // Set the header. the last parameter is 0, indicating that the returned value does not contain the header, and 1 indicates that the returned value contains the header. Curl_setopt ($ curl, CURLOPT_HEADER, 0 ); // Set the specific header of the browser. optional. if required Curl_setopt ($ ch, CURLOPT_HTTPHEADER, array ( "User-Agent: {'mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv: 1.9.1.6) Gecko/20091201 Firefox/3.5.6 (. net clr 3.5.30729 )'}", "Accept-Language: {en-us, en; q = 0.5 }" )); // Or set only the user-agent. optional. if required Curl_setopt ($ curl, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv: 1.8.1.1) Gecko/20061204 Firefox/2.0.0.1 "); // Set the cURL parameter. The result must be saved to the string or output to the screen. 1 indicates that the result is saved to the string. Curl_setopt ($ curl, CURLOPT_RETURNTRANSFER, 1 ); // When the page content is not required, set it to 1. the default value is 0. Curl_setopt ($ ch, CURLOPT_NOBODY, 1 ); // Run cURL, request webpage, save in $ data $ Data = curl_exec ($ curl ); // Close the URL request Curl_close ($ curl ); // Check for errors // During comparison, we use "= FALSE" instead of "= FALSE", because we need to distinguish 'null output' and 'Boolean false' If ($ output = FALSE ){ Echo "cURL Error:". curl_error ($ ch ); } // Obtain information $ Info = curl_getinfo ($ ch ); Echo 'get '. $ info ['URL'].' time consumed '. $ info ['total _ time']. 'second '; /*... The returned array contains the following information: "Url" // resource network address "Content_type" // content encoding "Http_code" // HTTP status code "Header_size" // header size "Request_size" // request size "Filetime" // file creation time "Ssl_verify_result" // SSL verification result "Redirect_count" // jump Technology "Total_time" // total time consumed "Namelookup_time" // DNS query time "Connect_time" // waiting for connection time "PRetransfer_time" // pre-transmission preparation time "Size_upload" // size of the uploaded data "Size_download" // size of the downloaded data "Speed_download" // download speed "Speed_upload" // upload speed "Download_content_length" // The length of the downloaded content "Upload_content_length" // length of the uploaded content "Starttransfer_time" // start time of transmission "Redirect_time" // time consumed by redirection */

Curl implements POST data submission

Http post implementation

The code is as follows:

// Extract data from the post Extract ($ _ POST ); // Set POST variables $ Url = 'http: // www. bKjia. c0m '; $ Fields = array ( 'Lname' => urlencode ($ last_name ), 'Fname' => urlencode ($ first_name ), 'Title' => urlencode ($ title ), 'Company' => urlencode ($ institution ), 'Age' => urlencode ($ age ), 'Email '=> urlencode ($ email ), 'Phone' => urlencode ($ phone) ); // Url-ify the data for the POST Foreach ($ fields as $ key => $ value) {$ fields_string. = $ key. '='. $ value .'&';} Rtrim ($ fields_string ,'&'); // Open connection $ Ch = curl_init (); // Set the url, number of POST vars, POST data Curl_setopt ($ ch, CURLOPT_URL, $ url ); Curl_setopt ($ ch, CURLOPT_POST, count ($ fields )); Curl_setopt ($ ch, CURLOPT_POSTFIELDS, $ fields_string ); // Execute post $ Result = curl_exec ($ ch ); // Close connection Curl_close ($ ch );
