지원 프로토콜/래퍼 목록

다음은 fopen()과 copy() 등의 파일시스템 함수용으로 내장된 PHP의 다양한 URL 스타일 프로토콜의 목록이다. 이런 래퍼들은 물론, PHP 4.3.0에서는, PHP 스크립트와 stream_wrapper_register()를 사용하여 자신의 래퍼를 작성할 수 있다.

파일시스템

PHP의 모든 버전. 특히 PHP 4.3.0부터는 file:// 사용.

/path/to/file.ext
relative/path/to/file.ext
fileInCwd.ext
C:/path/to/winfile.ext
C:\path\to\winfile.ext
\\smbserver\share\path\to\winfile.ext
file:///path/to/file.ext

file://은 PHP에서 사용하는 기본 래퍼로, 로컬 파일시스템을 표현합니다. 상대 경로(/, \, \\, 윈도우 드라이브 문자로 시작하지 않는 경로)를 지정하면, 경로는 현재 작업 디렉토리로부터 적용합니다. 대부분의 경우에, 변경하지 않는 한 이는 스크립트가 존재하는 디렉토리입니다. CLI sapi를 사용할 때, 디렉토리의 기본값은 스크립트를 호출한 위치입니다.

fopen()과 file_get_contents() 등의 몇몇 함수는 include_path의 상대 경로도 검색합니다.

**래퍼 요약**
속성	지원
allow_url_fopen으로 제한	No
읽기 허용	Yes
쓰기 허용	Yes
추가 허용	Yes
동시 읽기/쓰기 허용	Yes
stat() 지원	Yes
unlink() 지원	Yes
rename() 지원	Yes
mkdir() 지원	Yes
rmdir() 지원	Yes

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

If you want to talk to serial ports, on Linux or windows, there is some good discussion of it here:

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         = 127.0.0.1

        port         = 12345

        wait         = no

        user         = apache

        group        = apache

        instances    = 10

        server       = /usr/local/bin/php

        server_args  = -n [your php file here]

        only_from    = 127.0.0.1 #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.

followup:



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



xhttp.setRequestHeader('Content-Type',

'application/x-www-form-urlencoded');

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

parse_str($roughHTTPPOST);



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;

      xhttp.open("POST", "http://<?php echo $_SERVER['SERVER_NAME'] ?>/webservices/ws_service.php", true);

      // send the call with args

      xhttp.send(Args);



PHP Code:

    //read the raw data in

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

    //parse it into vars

    parse_str($roughHTTPPOST);

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

<?php



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



?>



Then you can parse the XML like this:



<?php



$xml = xml_parser_create();



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



xml_parser_free($xml);



$data = "";



foreach($vs as $v){



        if($v['level'] == 3 && $v['type'] == 'complete')

                $data .= "\n".$v['tag']." -> ".$v['value'];

}



echo $data;



?>



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.



<?php

$fo = 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");



fclose($fo);

fclose($fs);

?>



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 http://www.zevils.com/cgi-bin/viewcvs.cgi/libsmbclient-php/ (tarball link at the end).

When opening php://output in append mode you get an error, the way to do it:

$fp=fopen("php://output","w");

fwrite($fp,"Hello, world !<BR>\n");

fclose($fp);

The contants:



* STDIN

* STDOUT

* STDERR



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.
