Supported Protocols and Wrappers

PHP comes with many built-in wrappers for various URL-style protocols for use with the filesystem functions such as fopen(), copy(), file_exists() and filesize(). In addition to these wrappers, it is possible to register custom wrappers using the stream_wrapper_register() function.

Hinweis: The URL syntax used to describe a wrapper only supports the scheme://... syntax. The scheme:/ and scheme: syntaxes are not supported.

You can decompress (gzip) a input stream by combining wrappers:

eg:  $x = file_get_contents("compress.zlib://php://input");

I used this method to decompress a gzip stream that was pushed to my webserver

Not only are STDIN, STDOUT, and STDERR only allowed for CLI programs, but they are not allowed for programs that are read from STDIN. That can confuse you if you try to type in a simple test program.

to create a raw tcp listener system i use the following:

xinetd daemon with config like:
service test
        disable      = no
        type         = UNLISTED
        socket_type  = stream
        protocol     = tcp
        bind         =
        port         = 12345
        wait         = no
        user         = apache
        group        = apache
        instances    = 10
        server       = /usr/local/bin/php
        server_args  = -n [your php file here]
        only_from    = #gotta love the security#
        log_type     = FILE /var/log/phperrors.log
        log_on_success += DURATION

now use fgets(STDIN) to read the input. Creates connections pretty quick, works like a charm.Writing can be done using the STDOUT, or just echo. Be aware that you're completely bypassing the webserver and thus certain variables will not be available.

I found that if I added this line to the AJAX call, the values would show up in the $_POST

Example of how to use the php://input to get raw post data

//read the raw data in
$roughHTTPPOST = file_get_contents("php://input");
//parse it into vars

if you do readfile("php://input") you will get the length of the post data

In trying to do AJAX with PHP and Javascript, I came upon an issue where the POST argument from the following javascript could not be read in via PHP 5 using the $_REQUEST or $_POST. I finally figured out how to read in the raw data using the php://input directive.
Javascript code:
      //create request instance     
      xhttp = new XMLHttpRequest();
      // set the event handler
      xhttp.onreadystatechange = serviceReturn;
      // prep the call, http method=POST, true=asynchronous call
      var Args = 'number='+NbrValue;"POST", "http://<?php echo $_SERVER['SERVER_NAME'] ?>/webservices/ws_service.php", true);
      // send the call with args

PHP Code:
    //read the raw data in
    $roughHTTPPOST = file_get_contents("php://input");
    //parse it into vars

For reading a XML stream, this will work just fine:

= file_get_contents('php://input');


Then you can parse the XML like this:


= xml_parser_create();

xml_parse_into_struct($xml, $arq, $vs);


$data = "";

$vs as $v){

$v['level'] == 3 && $v['type'] == 'complete')
$data .= "\n".$v['tag']." -> ".$v['value'];



PS.: This is particularly useful for receiving mobile originated (MO) SMS messages from cellular phone companies.

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.

Example use:

$httprawpostdata = file_get_contents("php://input");

When reading a base64 encoded stream using php://input, be aware that you do not need to decode it, it will automatically be done for you.

php://stdin supports fseek() and fstat() function call,
while php://input doesn't.

Be aware that contrary to the way this makes it sound, under Apache, php://output and php://stdout don't point to the same place.

= fopen('php://output', 'w');
$fs = fopen('php://stdout', 'w');

fputs($fo, "You can see this with the CLI and Apache.\n");
fputs($fs, "This only shows up on the CLI...\n");


Using the CLI you'll see:
  You can see this with the CLI and Apache.
  This only shows up on the CLI...

Using the Apache SAPI you'll see:
  You can see this with the CLI and Apache.

If you're looking for a unix based smb wrapper there isn't one built in,  but I've had luck with (tarball link at the end).

When opening php://output in append mode you get an error, the way to do it:
fwrite($fp,"Hello, world !<BR>\n");

The contants:


Were introduced in PHP 4.3.0 and are synomous with the fopen('php://stdx') result resource.

I find using file_get_contents with php://input is very handy and efficient. Here is the code:

$request = "";
$request = file_get_contents("php://input");

I don't need to declare the URL filr string as "r". It automatically handles open the file with read.

I can then use this $request string to your XMLparser as data.

[ Editor's Note: There is a way to know.  All response headers (from both the final responding server and intermediate redirecters) can be found in $http_response_header or stream_get_meta_data() as described above. ]

If you open an HTTP url and the server issues a Location style redirect, the redirected contents will be read but you can't find out that this has happened.

So if you then parse the returned html and try and rationalise relative URLs you could get it wrong.
