There are two methods to choose from: First: handwritten code. Second: Use the HttpClient php class library
The first method:

Copy the code The code is as follows:

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

The second method is: use the httpclient class

Copy the code The code is as follows:

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

Using the httpclient class library, you can download the latest class library from the official address: http://scripts.incutio. com/httpclient/index.php
Attach some php httpclient and several other usages
Static method to obtain web pages:

Copy code The code is as follows :

$pageContents = HttpClient::quickGet('http://bankcha.com')

　Get method gets

Copy code The code is as follows:

 
$client = new HttpClient('bankcha.com'); 
if (!$client->get('/')) { 
die('An error occurred: '. $client->getError()); 
} 
$pageContents = $client->getContent(); 
 Get method with debugging 
 PHP code 
$client = new HttpClient('bankcha.com'); 
$client->setDebug(true); 
if (!$client->get('/')) { 
die('An error occurred : '.$client->getError()); 
} 
$pageContents = $client->getContent(); 
 Get method with automatic redirection 
 PHP code 
 $ client = new HttpClient('www.bankcha.com'); 
$client->setDebug(true); 
if (!$client->get('/')) { 
die ('An error occurred: '.$client->getError()); 
} 
$pageContents = $client->getContent(); 
 Check if the page exists
 PHP code
$client = new HttpClient('bankcha.com'); 
$client->setDebug(true); 
if (!$client->get('/thispagedoesnotexist')) { 
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('bankcha.com' ); 
$client->setDebug(true); 
$client->setUserAgent('Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.3a) Gecko/20021207 '); 
if (!$client->get('/')) { 
die('An error occurred: '.$client->getError()); 
} 
$pageContents = $client->getContent(); 
 Login verification and request a web page
 PHP code
$client = new HttpClient('bankcha.com'); 
$client-> ;post('/login.php', array( 
'username' => 'Simon', 
'password' => 'ducks' 
)); 
if (!$ client->get('/private.php')) { 
die('An error occurred: '.$client->getError()); 
} 
$pageContents = $client- >getContent(); 
 HTTP Authorization
 PHP code
$client = new HttpClient('bankcha.com'); 
$client->setAuthorization('Username', 'Password') ; 
if (!$client->get('/')) { 
die('An error occurred: '.$client->getError()); 
} 
$ pageContents = $client->getContent(); 
 Output header information 
 PHP code 
$client = new HttpClient('bankcha.com'); 
if (!$client->get ('/')) { 
die('An error occurred: '.$client->getError()); 
} 
print_r($client->getHeaders()); 
 Set the maximum number of redirects within a domain 
 PHP code 
$client = new HttpClient('www.bankcha.com'); 
$client->setDebug(true); 
$client- >setMaxRedirects(3); 
$client->get('/'); 

php fsockopen fakes post and get methods
fsockopen fakes post and get methods, if You are looking for PHP processing code that fakes post and get methods. This one is good.

Copy code The code is as follows:

 
//fsocket simulated post submission
$purl = "http://localhost/netphp/test2.php?uu=rrrrrrrrrr"; 
print_r(parse_url($url)); 
sock_post($purl,"uu=55555555555555555"); 
/ /fsocket simulates get submission
function sock_get($url, $query) 
{ 
$info = parse_url($url); 
$fp = fsockopen($info["host"], 80 , $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=rrrrrrrrrrrrrr"); 
function sock_post($url, $query) 
{ 
$info = parse_url($url); 
$fp = fsockopen($info["host"] , 80, $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; 
} 
} 
?>
