PHP simulation post behavior code summary_PHP tutorial

GET behavior is relatively simple, while POST is more complex. There are two methods to choose from: First: handwritten code. Second: Use the HttpClient php class library

First method:

PHP code
$flag = 0;
//Data to post                                        $argv = array(    
var1=>abc,  
var2=>How are you);  
//Construct the string to be posted
foreach ($argv as $key=>$value) {                                         if ($flag!=0) {
               $params .= "&";                                             $flag = 1;                                                                                                 $params.= $key."="; $params.= urlencode($value); $params.= $key."="; $params.= urlencode($value);        $flag = 1;                                                                                                   $length = strlen($params);                                                                                                                                                                                                                     $fp = fsockopen("127.0.0.1",80,$errno,$errstr,10) or exit($errstr."--->".$errno); //Construct the header of the post request
$header = "POST /mobile/try.php HTTP/1.1"; $header = "POST /mobile/try.php HTTP/1.1";
$header .= "Host:127.0.0.1"; $header .= "Host:127.0.0.1";
$header .= "Referer:/mobile/sendpost.php"; $header .= "Referer:/mobile/sendpost.php";
$header .= "Content-Type: application/x-www-form-urlencoded"; $header .= "Content-Type: application/x-www-form-urlencoded";
$header .= "Content-Length: ".$length.""; $header .= "Content-Length: ".$length."";
        $header .= "Connection: Close";                                //Add the string of the post
$header .= $params.""; $header .= $params."";
//Send post data                                                                                                                                                                $inheader = 1;                               While (!feof($fp)) {                                                                          $line = fgets($fp,1024); //Remove the header of the request packet and only display the return data of the page                                  If ($inheader && ($line == " " || $line == "")) {   
                        $inheader = 0;                                                                                                                               if ($inheader == 0) {                                                                           echo $line;                                                                                                                                                                            fclose($fp);                                        ?> 

The second method is: use httpclient class

PHP code
$pageContents = HttpClient::quickPost(http://example.com/someForm, array(    
name => Some Name, 
email => email@example.com
));

To use the httpclient class library, you can go to the official website to download the latest class library. The official address is: http://scripts.incutio.com/httpclient/index.php

Attach some other uses of php httpclient

Static method to obtain web page:

PHP code
$pageContents = HttpClient::quickGet(http://example.com/);  

Get method gets

PHP code
$client = new HttpClient(example.com); 
if (!$client->get(/)) {    
Die(An error occurred: .$client->getError()); Die(An error occurred: .$client->getError());
}       
$pageContents = $client->getContent();

Get method with debugging

PHP code
$client = new HttpClient(example.com);    
$client->setDebug(true);                             if (!$client->get(/)) {    
Die(An error occurred: .$client->getError()); Die(An error occurred: .$client->getError());
}       
$pageContents = $client->getContent();

Get method with automatic redirection

PHP code

$client = new HttpClient(www.amazon.com);   
$client->setDebug(true);                             if (!$client->get(/)) {          
Die(An error occurred: .$client->getError()); Die(An error occurred: .$client->getError());
}       
$pageContents = $client->getContent();

Check if the page exists

PHP code

$client = new HttpClient(example.com);    

$client->setDebug(true);                             if (!$client->get(/thispagedoesnotexist)) {     
Die(An error occurred: .$client->getError()); Die(An error occurred: .$client->getError());
}       
if ($client->getStatus() == 404) {     
echo Page does not exist!; }       
$pageContents = $client->getContent();

Fake client

PHP code

$client = new HttpClient(exa
