Installing and opening the Curl PHP extension under Tlinux (CentOS)

0x01 Background Introduction

CURL is a tool that uses URL syntax to transfer files and data, and supports many protocols, such as HTTP, FTP, Telnet, and so on. PHP also supports the CURL library.

0x001 using Curl extension in PHP

Basic steps for creating a curl request in PHP:
(1) initialization
Curl_init ()

(2) Setting variables
curl_setopt (). The most important thing is here. There is a long list of curl parameters that can be set to specify the details of the URL request. It may be difficult to read them all at once and to understand them, so today we'll just try some of the more commonly used and more useful options.

(3) Execute and get results
Curl_exec ()

(4) Release curl handle
Curl_close ()

0x002 PHP for Get and post in Curl

Get Mode implementation:

Initialize $ch = Curl_init ();　　Set options, including URL curl_setopt ($ch, Curlopt_url, "Http://liuqunying.ok");　　curl_setopt ($ch, Curlopt_returntransfer, 1);　　curl_setopt ($ch, Curlopt_header, 0);　　Executes and obtains the contents of the HTML document $output = curl_exec ($ch);　　Release Curl handle Curl_close ($ch); Print the obtained data print_r ($output);

Post Mode implementation

$url = "http://myserver.lqy/web_services.php";　　$post _data = Array ("username" = "Qunyingliu", "key" = "!234s67b");　　$ch = Curl_init ();　　curl_setopt ($ch, Curlopt_url, $url);　　curl_setopt ($ch, Curlopt_returntransfer, 1);　　POST Data curl_setopt ($ch, Curlopt_post, 1);　　Post variables curl_setopt ($ch, Curlopt_postfields, $post _data);　　$output = curl_exec ($ch);　　Curl_close ($ch); Print the obtained data print_r ($output);
