PHP Fsockopen imitate Post and get detailed _php tutorial

In PHP fsockopen function can imitate the user to visit some Web site and can also bring some common information, if the browser, Ip,post,get and so on data, I will introduce each of you.

If you want to use the Fsockopen function we must set the Allow_url_fopen = on to ON in PHP.ini.

Cases

Fsockopen () Example

The code is as follows	Copy Code
$fp = Fsockopen ("www.example.com", $errno, $errstr, 30); if (! $fp) { echo "$errstr ($errno) n "; } else { $out = "Get/http/1.1rn"; $out. = "HOST:WWW.EXAMPLE.COMRN"; $out. = "Connection:closernrn"; Fwrite ($fp, $out); while (!feof ($fp)) { Echo fgets ($FP, 128); } Fclose ($FP); } ?>

Forge Post

POST http request (URL) and get return value

The code is as follows

Copy Code

$srv _ip = ' 192.168.1.5 ';//your target service address. $srv _port = 80;//Port $url = ' http://localhost/fsock.php '; Receive your post URL specific address $fp = "; $errno = 0;//error Handling $ERRSTR = ";//error handling $timeout = 10;//How long it has not been connected to the interruption $post _str = "Username=demo&password=hahaha";//content to be submitted. Open the Socket link for your network. $fp = Fsockopen ($srv _ip, $srv _port, $errno, $errstr, $timeout); if (! $fp) { Echo (' FP fail '); } $content _length = strlen ($post _str); $post _header = "Post $url http/1.1rn"; $post _header. = "CONTENT-TYPE:APPLICATION/X-WWW-FORM-URLENCODEDRN"; $post _header. = "User-agent:msiern"; $post _header. = "Host:". $srv _ip. " RN "; $post _header. = "Content-length:". $content _length. " RN "; $post _header. = "Connection:closernrn"; $post _header. = $post _str. " Rnrn "; Fwrite ($fp, $post _header); $inheader = 1; while (!feof ($fp)) {//test file pointer is to the end of the file location $line = fgets ($fp, 1024); Remove the header information from the request package if ($inheader && ($line = = "N" | | $line = = "rn") { $inheader = 0; } if ($inheader = = 0) { Echo $line; } } Fclose ($FP); Unset ($line); ?>

Brief description: The second line of code is your IP address or domain name, the fourth line is the specific address of the page you want to post, this example uses fsock.php,fsock.php content as follows:

The code is as follows	Copy Code
echo "Username:". $_post[' username ']. " "; echo "Password:". $_post[' password '); ?>

The result is:

Username:demo

Password:hahaha

Forge get

At the same time forge the Post,get method.

The code is as follows

Copy Code

Fsocket Analog Post Submission $purl = "Http://localhost/netphp/test2.php?uu=rrrrrrrrrrrr"; Print_r (Parse_url ($url)); Sock_post ($purl, "uu=55555555555555555"); Fsocket Analog Get Commit function Sock_get ($url, $query) { $info = Parse_url ($url); $fp = Fsockopen ($info ["host"], $errno, $ERRSTR, 3); $head = "GET". $info [' Path ']. "?". $info ["Query"]. " Http/1.0rn "; $head. = "Host:". $info [' Host ']. " RN "; $head. = "RN"; $write = fputs ($fp, $head); while (!feof ($FP)) { $line = Fread ($fp, 4096); Echo $line; } } Sock_post ($purl, "uu=rrrrrrrrrrrrrrrr"); function Sock_post ($url, $query) { $info = Parse_url ($url); $fp = Fsockopen ($info ["host"], $errno, $ERRSTR, 3); $head = "POST". $info [' Path ']. "?". $info ["Query"]. " Http/1.0rn "; $head. = "Host:". $info [' Host ']. " RN "; $head. = "referer:http://". $info [' Host ']. $info [' Path ']. RN "; $head. = "CONTENT-TYPE:APPLICATION/X-WWW-FORM-URLENCODEDRN"; $head. = "Content-length:". strlen (Trim ($query)). " RN "; $head. = "RN"; $head. = Trim ($query); $write = fputs ($fp, $head); while (!feof ($FP)) { $line = Fread ($fp, 4096); Echo $line; } } ?>
