最近用到，記錄一下

首先先寫一支接收端，只是單純的把POST參數印出來

api.php
<?php

if ($_POST)
{
    print_r($_POST) ;
}

?>

另外寫一支put.php

<?php

$post = array('name'=>'Joe', gender=>"male") ;  //post

$host = 'localhost' ;

$port = 80 ;

$errno = 0 ;  //錯誤碼會回存這裡。

$errstr = '' ;  //錯誤資訊會回存這裡

$timeout = 5 ;

foreach ($post as $k => $v)
{
    $strPost .= ('&'.$k.'='.$v) ;
}

$request.="POST ".'/sock/api.php'." HTTP/1.1\n"; 
$request.="Host: ".$host."\n"; 
$request.="Referer: ".$_SERVER["SCRIPT_URI"]."\n"; 
$request.="Content-type: application/x-www-form-urlencoded\n"; 
$request.="Content-length: ".strlen($strPost)."\n"; 
$request.="Connection: close\n"; 
$request.="\n"; 
$request.=$strPost."\n";

$fp = fsockopen($host, $port, $errno, $errstr, $timeout) ;
fputs($fp, $request) ;

while ($result = fgets($fp, 1024))
{
    if ($result == "\r\n")
    {
        break ;  //表示表頭結束
    }
}

while(!feof($fp)) 
{ 
    $result .= fgets($fp, 128); 
}

fclose($fp); 
echo $result ;
