file_get_contents

(PHP 4 >= 4.3.0, PHP 5)

file_get_contents — Liest die gesamte Datei in einen String

Beschreibung

string file_get_contents ( string $filename [, int $use_include_path [, resource $context ]] )

Diese Funktion ist mit file() identisch, außer dass file_get_contents() die Datei in einem String zurückgibt.

file_get_contents() ist die bevorzugte Methode, um die Inhalte einer Datei in einen String einzulesen. Falls von Ihrem Betriebssystem unterstützt, verwendet es Memory Mapping Techniken, um die Performance zu erhöhen.

Hinweis: Diese Funktion ist binary safe.

Tipp

Mit dieser Funktion können Sie eine URL als Dateinamen verwenden, falls Sie fopen wrappers ermöglicht haben. Mehr Details dazu, wie Sie den Dateinamen angeben müssen finden Sie bei fopen(). Eine Liste der unterstützten URL Protokolle finden Sie unter List of Supported Protocols/Wrappers.

Hinweis: Die Kontext-Unterstützung wurde in PHP 5.0.0 eingeführt.

Siehe auch: fgets(), file(), fread(), include() und readfile().

  # Note: if the file cannot be opened then file_get_contents will attempt to warn the following:

Setting the timeout properly without messing with ini values:





<?php


$ctx = stream_context_create(array(


    'http' => array(


        'timeout' => 1


        )


    )


);


file_get_contents("http://example.com/", 0, $ctx);


?>

This is a nice and simple substitute to get_file_contents() using curl, it returns FALSE if $contents is empty.



<?php

function curl_get_file_contents($URL)

    {

        $c = curl_init();

        curl_setopt($c, CURLOPT_RETURNTRANSFER, 1);

        curl_setopt($c, CURLOPT_URL, $URL);

        $contents = curl_exec($c);

        curl_close($c);



        if ($contents) return $contents;

            else return FALSE;

    }

?>



Hope this help, if there is something wrong or something you don't understand let me know :)

I decided to make a similar function to this, called file_post_contents, it uses POST instead of GET to call, kinda handy...



<?php

function file_post_contents($url,$headers=false) {

    $url = parse_url($url);



    if (!isset($url['port'])) {

      if ($url['scheme'] == 'http') { $url['port']=80; }

      elseif ($url['scheme'] == 'https') { $url['port']=443; }

    }

    $url['query']=isset($url['query'])?$url['query']:'';



    $url['protocol']=$url['scheme'].'://';

    $eol="\r\n";



    $headers =  "POST ".$url['protocol'].$url['host'].$url['path']." HTTP/1.0".$eol. 

                "Host: ".$url['host'].$eol. 

                "Referer: ".$url['protocol'].$url['host'].$url['path'].$eol. 

                "Content-Type: application/x-www-form-urlencoded".$eol. 

                "Content-Length: ".strlen($url['query']).$eol.

                $eol.$url['query'];

    $fp = fsockopen($url['host'], $url['port'], $errno, $errstr, 30); 

    if($fp) {

      fputs($fp, $headers);

      $result = '';

      while(!feof($fp)) { $result .= fgets($fp, 128); }

      fclose($fp);

      if (!$headers) {

        //removes headers

        $pattern="/^.*\r\n\r\n/s";

        $result=preg_replace($pattern,'',$result);

      }

      return $result;

    }

}

?>

Seems file looks for the file inside the current working (executing) directory before looking in the include path, even with the FILE_USE_INCLUDE_PATH flag specified.



Same behavior as include actually.



By the way I feel the doc is not entirely clear on the exact order of inclusion (see include). It seems to say the include_path is the first location to be searched, but I have come across at least one case where the directory containing the file including was actually the first to be searched.



Drat.

If you're having problems with binary and hex data:



I had a problem when trying to read information from a ttf, which is primarily hex data. A binary-safe file read automatically replaces byte values with their corresponding ASCII characters, so I thought that I could use the binary string when I needed readable ASCII strings, and bin2hex() when I needed hex strings.



However, this became a problem when I tried to pass those ASCII strings into other functions (namely gd functions). var_dump showed that a 5-character string contained 10 characters, but they weren't visible. A binary-to-"normal" string conversion function didn't seem to exist and I didn't want to have to convert every single character in hex using chr().



I used unpack with "c*" as the format flag to see what was going on, and found that every other character was null data (ordinal 0). To solve it, I just did



str_replace(chr(0), "", $string);



which did the trick.



This took forever to figure out so I hope this helps people reading from hex data!

you'll find the http response headers in: $http_response_header

[Editors note: As of PHP 5.2.1 you can specify `timeout` context option and pass the context to file_get_contents()]





The only way I could get get_file_contents() to wait for a very slow http request was to set the socket timeout as follows.





 ini_set('default_socket_timeout',    120);    


$a = file_get_contents("http://abcxyz.com");





Other times like execution time and input time had no effect.

Use the previous example if you want to request the server for a special part of the content, IF and only if the server accepts the method.

If you want a simple example to ask the server for all the content, but only save a portion of it, do it this way:

<?

$content=file_get_contents("http://www.google.com",FALSE,NULL,0,20);

echo $content;

?>



This will echo the 20 first bytes of the google.com source code.

the bug #36857 was fixed.

http://bugs.php.net/36857



Now you may use this code,to fetch the partial content like this:

<?php

$context=array('http' => array ('header'=> 'Range: bytes=1024-', ),);

$xcontext = stream_context_create($context);

$str=file_get_contents("http://www.fcicq.net/wp/",FALSE,$xcontext);

?>

that's all.

If, like me, you are on a Microsoft network with ISA server and require NTLM authentication, certain applications will not get out of the network. SETI@Home Classic and PHP are just 2 of them.



The workaround is fairly simple.



First you need to use an NTLM Authentication Proxy Server. There is one written in Python and is available from http://apserver.sourceforge.net/. You will need Python from http://www.python.org/.



Both sites include excellent documentation.



Python works a bit like PHP. Human readable code is handled without having to produce a compiled version. You DO have the opportunity of compiling the code (from a .py file to a .pyc file).



Once compiled, I installed this as a service (instsrv and srvany - parts of the Windows Resource Kit), so when the server is turned on (not logged in), the Python based NTLM Authentication Proxy Server is running.



Then, and here is the bit I'm really interested in, you need to tell PHP you intend to route http/ftp requests through the NTLM APS.



To do this, you use contexts.



Here is an example.



<?php



// Define a context for HTTP.

$aContext = array(

    'http' => array(

        'proxy' => 'tcp://127.0.0.1:8080', // This needs to be the server and the port of the NTLM Authentication Proxy Server.

        'request_fulluri' => True,

        ),

    );

$cxContext = stream_context_create($aContext);



// Now all file stream functions can use this context.



$sFile = file_get_contents("http://www.php.net", False, $cxContext);



echo $sFile;

?>



Hopefully this helps SOMEONE!!!

This functionality is now implemented in the PEAR package PHP_Compat.
