PHP input Stream Php://input example explain _php skills

For the php://input introduction, the PHP official manual document has a very clear overview of it in a word.
"Php://input allows to read raw POST data. It is a less memory intensive alternative to$http_raw_post_data and does no need any special php.ini. Php://input is isn't available with enctype= "Multipart/form-data".

Translation over, is this:
"Php://input can read post data that has not been processed. Compared to $http_raw_post_data, it brings less pressure on memory and does not require special php.ini settings. Php://input cannot be used for Enctype=multipart/form-data "
Summarized as follows:

• 1), Coentent-type only in application/x-www-data-urlencoded and multipart/form-data two cases, PHP will be the HTTP request packet in the corresponding data into the global variable $_ POST
• 2, PHP can not recognize the type of Content-type, the HTTP request package will be filled with the corresponding data in the variable $http_raw_post_data
• 3), only when Coentent-type is Multipart/form-data, PHP does not fill in the HTTP request packet of the corresponding data into the php://input, otherwise will be. The length of the fill, specified by Coentent-length.
• 4), only when Content-type is application/x-www-data-urlencoded, php://input data is consistent with $_post data.
• 5), php://input data is always the same as $http_raw_post_data, but php://input more effective than $http_raw_post_data, and do not need special settings php.ini
• 6, PHP will be the path of the Query_path part of the field, fill in the global variable $_get. Normally, the body is empty for the HTTP request submitted by the Get method.

To sum up, when using $_post to get callback data from an app or some interface, use Php://input to try

1. Accept XML data

Sending XML data
$xml = ' <xml>xmldata</xml> ';//the XML $url to send 
= ' http://localhost/test/getXML.php '; Receive XML address 
$header = ' content-type:text/xml ';//define Content-type as XML 
$ch = Curl_init ();//Initialize Curl 
curl_setopt ($ch, Curlopt_url, $url);/set link 
curl_setopt ($ch, Curlopt_returntransfer, 1);//Set whether to return information 
curl_setopt ($ch, Curlopt_httpheader, $header);/Set HTTP header 
curl_setopt ($ch, Curlopt_post, 1);//Set to POST method 
curl_setopt ($ch, Curlopt_postfields, $xml);//post data 
$response = curl_exec ($ch);//Receive return information 
if (Curl_errno ($ch)) {//error message is displayed 
print Curl_error ($ch); 
Curl_close ($ch); Close Curl Link 
echo $response//Display return information 


//php with file_get_contents ("Php://input") or $http_raw_post_ Data can receive
$xmldata = file_get_contents ("Php://input") of XML; 
$data = (array) simplexml_load_string ($xmldata);

Send

@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 =; 
$path = '/image.php '; 
$fp = Fsockopen ($host, $port, $error _no, $error _desc); 
if ($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; 
}

Receive

/**

error_reporting (e_all);

function get_contents () {
 $xmlstr = file_get_contents ("Php://input");
 $filename =file_put_contentsxmltime (). PNG ';
 if (($filename, $str)) {

3: Get HTTP request text

/**
 * Get HTTP request original
 * @return string
/function Get_http_raw () {
 $raw = ';
 (1) Request line 
 $raw. = $_server[' Request_method ']. ' ' . $_server[' Request_uri ']. ' ' . $_server[' Server_protocol ']. "\ r \ n";
 (2) Request Headers 
 foreach ($_server as $key => $value) {
 if (substr ($key, 0, 5) = = ' Http_ ') {
  $key = s Ubstr ($key, 5);
  $key = Str_replace (' _ ', '-', $key);
  $raw. = $key. ': ' . $value. "\ r \ n";
 }
 }
 (3) Empty line 
 $raw. = "\ r \ n";
 (4) Request Body 
 $raw. = file_get_contents (' php://input ');
 return $raw;
}

The above is for PHP input stream Three small chestnuts, the purpose is to help you more accurately understand the PHP input stream, I hope we have a harvest.
