For php: // input introduction, the PHP official manual provides a clear overview of it.
"Php: // input allows you to read raw POST data. it is a less memory intensive alternative to $ HTTP_RAW_POST_DATA and does not need any special php. ini directives. php: // input is not available with enctype = "multipart/form-data ".

The translation is like this:
"Php: // input can read POST data that has not been processed. Compared with $ HTTP_RAW_POST_DATA, it puts less pressure on memory and does not require special php. ini settings. Php: // input cannot be used for enctype = multipart/form-data"
Summary:

• 1) Coentent-Type can only be set to application/x-www-data-urlencoded or multipart/form-data, PHP will fill in the corresponding data in the http request packet with the global variable $ _ POST
• 2) When PHP cannot recognize the Content-Type, it will fill in the corresponding data in the http request package with the variable $ HTTP_RAW_POST_DATA
• 3) when the Coentent-Type is multipart/form-data, PHP will not fill in the corresponding data in the http request packet in php: // input; otherwise, it will be used in other cases. Length specified by Coentent-Length.
• 4) php: // input data is consistent with $ _ POST data only when the Content-Type is application/x-www-data-urlencoded.
• 5) php: // the input data is always the same as $ HTTP_RAW_POST_DATA, but php: // input is more efficient than $ HTTP_RAW_POST_DATA, and php. ini does not need to be specially set.
• 6) PHP will fill in the query_path part of the PATH field with the global variable $ _ GET. Normally, the http request submitted by the GET method has no body.

In summary, when $ _ POST cannot obtain the callback data from the APP or some interfaces, use php: // input.

1. accept xml data

// Send xml data $ xml ='
 
  
Xmldata
 '; // The xml $ url to be sent = '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 the link curl_setopt ($ ch, CURLOPT_RETURNTRANSFER, 1); // Set whether to return information curl_setopt ($ ch, CURLOPT_HTTPHEADER, $ header); // Set the HTTP header curl_setopt ($ ch, CURLOPT_POST, 1); // Set it to the POST method curl_setopt ($ ch, CURLOPT_POSTFIELDS, $ xml ); // POST data $ response = curl_exec ($ ch); // receives the returned information if (curl_errno ($ ch )) {// print curl_error ($ ch);} curl_close ($ ch); // Close the curl link echo $ response; // display the returned information // use file_get_contents ("php: // input") or $ HTTP_RAW_POST_DATA to receive xml data $ xmldata = file_get_contents ("php: // input "); $ data = (array) simplexml_load_string ($ xmldata );

2. small programs that upload images to the server via mobile phones
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 = 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; }

Receive

/** *Recieve image data **/error_reporting(E_ALL);function get_contents() { $xmlstr= file_get_contents("php://input"); $filename=file_put_contentsxmltime().'.png'; if(($filename,$str)){ echo 'success'; }else{ echo 'failed'; }   }get_contents();

3: Get the original HTTP request

/*** Get the original HTTP request * @ 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 = substr ($ key, 5); $ key = str_replace (' _ ','-', $ key); $ raw. = $ key. ':'. $ value. "\ r \ n" ;}}// (3) empty row $ raw. = "\ r \ n"; // (4) request Body $ raw. = file_get_contents ('php: // input'); return $ raw ;}

The above are three small examples of PHP input streams. they aim to help you better understand the PHP input stream and hope you will gain some benefits.
