Simple test Instance

The code is as follows

Copy Code

<?php Initializes a CURL object $curl = Curl_init (); Set the URL you want to crawl curl_setopt ($curl, Curlopt_url, ' http://coolshell.cn '); Set Header curl_setopt ($curl, Curlopt_header, 1); Sets the curl parameter to require that the results be saved to the string or to the screen. curl_setopt ($curl, Curlopt_returntransfer, 1); Run Curl, request Web page $data = curl_exec ($curl); Close URL Request Curl_close ($curl); Show the data you get Var_dump ($data);

copy code

<?php $phoneNumber = ' 13912345678 '; $message = ' This is generated by curl and PHP '; $curlPost = ' pnumber= '. UrlEncode ($phoneNumber). ' &message= '. UrlEncode ($message). ' &submit=send '; $ch = Curl_init (); curl_setopt ($ch, Curlopt_url, ' http://www.example.com/sendSMS.php '); curl_setopt ($ch, Curlopt_header, 1); curl_setopt ($ch, Curlopt_returntransfer, 1); curl_setopt ($ch, Curlopt_post, 1); curl_setopt ($ch, Curlopt_postfields, $curlPost); $data = Curl_exec (); Curl_close ($ch); ?>

Now get to the point where Curl fake IP and source

1.php Code:

The code is as follows	Copy Code
$ch = Curl_init (); curl_setopt ($ch, Curlopt_url, "http://localhost/2.php"); curl_setopt ($ch, Curlopt_httpheader, Array (' x-forwarded-for:8.8.8.8 ', ' client-ip:8.8.8.8 '));//ip curl_setopt ($ch, Curlopt_referer, "http://www.111cn.net/"); Antecedents curl_setopt ($ch, Curlopt_header, 1); $out = curl_exec ($ch); Curl_close ($ch);

2.php Code:

code is as follows

copy code

function Getclientip () {     if (!empty ($_server[) http_client _ip "])         $ip = $_server[" Http_client_ip "];     Else if (!empty ($_server["http_x_forwarded_for"]))         $ip = $_server["http_x _forwarded_for "];     Else if (!empty ($_server["REMOTE_ADDR"))         $ip = $_server["REMOTE_ADDR"];     Else         $ip = "err";     return $ip; } Echo "IP:". Getclientip (). ""; echo "Referer:". $_server["Http_referer"];

1.php request 2.php, output result:

As for SSL, the HTTPS protocol, you just have to turn the http://in the Curlopt_url connection into https://. Of course, there is also a parameter called Curlopt_ssl_verifyhost can be set to verify the site.

For cookies, you need to know the following three parameters:

Curlopt_cookie, set a COOKIE in your face-to-face session
Curlopt_cookiejar, save a cookie when the session ends
Curlopt_cookiefile,cookie's file.
