/*不經過$_FILES提交圖片的方法*/php

$data = file_get_contents("php://input");json

php://input 是個能夠訪問請求的原始數據的只讀流。 POST 請求的狀況下，最好使用 php://input 來代替 $HTTP_RAW_POST_DATA，由於它不依賴於特定的 php.ini 指令。 並且，這樣的狀況下 $HTTP_RAW_POST_DATA 默認沒有填充， 比激活 always_populate_raw_post_data 潛在須要更少的內存。 enctype="multipart/form-data" 的時候 php://input 是無效的。 1, php://input 能夠讀取http entity body中指定長度的值,由Content-Length指定長度,無論是POST方式或者GET方法提交過來的數據。可是，通常GET方法提交數據 時，http request entity body部分都爲空。 2,php://input 與$HTTP_RAW_POST_DATA讀取的數據是同樣的，都只讀取Content-Type不爲multipart/form-data的數據。
學習筆記
 1，Coentent-Type僅在取值爲application/x-www-data-urlencoded和multipart/form-data兩種狀況下，PHP纔會將http請求數據包中相應的數據填入全局變量$_POST2，PHP不能識別的Content-Type類型的時候，會將http請求包中相應的數據填入變量$HTTP_RAW_POST_DATA3, 只有Coentent-Type爲multipart/form-data的時候，PHP不會將http請求數據包中的相應數據填入php://input，不然其它狀況都會。填入的長度，由Coentent-Length指定。 4，只有Content-Type爲application/x-www-data-urlencoded時，php://input數據纔跟$_POST數據相一致。 5，php://input數據老是跟$HTTP_RAW_POST_DATA相同，可是php://input比$HTTP_RAW_POST_DATA更湊效，且不須要特殊設置php.ini 6，PHP會將PATH字段的query_path部分，填入全局變量$_GET。一般狀況下，GET方法提交的http請求，body爲空。
 
例子
 1.php用file_get_contents("php://input")或者$HTTP_RAW_POST_DATA能夠接收xml數據
 好比：
  getXML.php;//接收XML地址
  
<?php

$xmldata = file_get_contents("php://input"); 
     $data = (array)simplexml_load_string($xmldata); 
?> 
 
  這裏的$data就是包含xml數據的數組，具體php解析xml數據更新詳細的方法
  sendXML.php
 
<?php
$xml = '<xml>xmldata</xml>';//要發送的xml 
$url = 'http://localhost/test/getXML.php';//接收XML地址 
$header = 'Content-type: text/xml';//定義content-type爲xml 
$ch = curl_init(); //初始化curl 
curl_setopt($ch, CURLOPT_URL, $url);//設置連接 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);//設置是否返回信息 
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);//設置HTTP頭 
curl_setopt($ch, CURLOPT_POST, 1);//設置爲POST方式 
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml);//POST數據 
$response = curl_exec($ch);//接收返回信息 
if(curl_errno($ch)){//出錯則顯示錯誤信息 
        printcurl_error($ch); 
     }
curl_close($ch); //關閉curl連接 
echo $response;//顯示返回信息 ?>

2.一個手機上傳圖片到服務器的小程序
  a. 上傳文件  
<?php
//@file phpinput_post.php 
$data=file_get_contents('btn.png'); 
     $http_entity_body = $data; 
     $http_entity_type = 'application/x-www-form-urlencoded'; 
     $http_entity_length = strlen($http_entity_body); 
     $host = '127.0.0.1'; 
     $port = 80; 
     $path = '/image.php'; 
     $fp = fsockopen($host, $port, $error_no, $error_desc, 30); 
     if($fp){fputs($fp, "POST {$path} HTTP/1.1\r\n"); 
        fputs($fp, "Host: {$host}\r\n"); 
        fputs($fp, "Content-Type: {$http_entity_type}\r\n"); 
        fputs($fp, "Content-Length: {$http_entity_length}\r\n"); 
        fputs($fp, "Connection: close\r\n\r\n"); 
        fputs($fp, $http_entity_body . "\r\n\r\n"); 
 
        while(!feof($fp)){$d .= fgets($fp, 4096); 
        }fclose($fp); 
        echo$d; 
     }?> 
 
  b. 接收文件
  
<?php
        /** 
         *Recieve image data 
        **/

error_reporting(E_ALL); 
 
     function get_contents(){
        $xmlstr= file_get_contents("php://input"); 
        $filename=time().'.png'; 
        if(file_put_contents($filename,$xmlstr)){
                echo'success'; 
            }else{
                echo'failed'; 
        }
    }
    get_contents(); 
?>

3.獲取HTTP請求原文
  
/** 
     * 獲取HTTP請求原文 
     * @return string 
     */function get_http_raw(){
        $raw = ''; 
 
     // (1) 請求行

$raw .= $_SERVER['REQUEST_METHOD'].''.$_SERVER['REQUEST_URI'].''.$_SERVER['SERVER_PROTOCOL']."\r\n"; 
 
     // (2) 請求Headers 
        foreach($_SERVERas$key => $value){if(substr($key, 0, 5) === 'HTTP_'){$key = substr($key, 5); 
         $key = str_replace('_', '-', $key); 
 
         $raw .= $key.': '.$value."\r\n"; 
        }}// (3) 空行 $raw .= "\r\n"; 
 
     // (4) 請求Body $raw .= file_get_contents('php://input'); 
 
     return$raw; 
}
