fake user agent?

[Anon]

I need to fake the user agent php uses when fopen'ing a url

Example

fopen("http://enthalpy.org/", r);

The webserver sees this request as the following:

127.31.33.7 - - [08/Apr/2002:18:27:47 -0500] "GET / HTTP/1.0" 200 2725 "-" "PHP/4.1.2"

The user agent is shown as "PHP/4.1.2"

I need to be able to change this, alot of sites deny user agents and this happens to be one that is denied on some very large sites.

This is really important and super easy to do
in perl i cant imagine it not being in php.

Here is a quick function I wrote up for retrieving webpages...

function openURL($host,$port,$page,$user_agent='PHP',$referer='',$withHeaders=FALSE) {
    // Open a connection to the webserver
    $fp = fsockopen($host,$port,$errno,$errstr,10);
    if(!$fp)
        return false;

    // Request the page
    fputs($fp,"GET $page HTTP/1.0\r\n");
    fputs($fp,"User-agent: $user_agent\r\n");
    if($referer)
        fputs($fp,"Referer: $referer\r\n");
    fputs($fp,"\r\n");

    // Read the response
    while(!feof($fp))
        $document .= fgets($fp,2048);

    if(!$withHeaders)
        list($headers,$document) = explode("\r\n\r\n",$document);

    // Close the Connection
    fclose($fp);

    return $document;
}

And here is an example of its usage...

$webpage_data = openURL("www.yoursite.com",80,"/","My Special Internet Browser","www.referer.com",FALSE);

You MUST specify a page to load. If you want to get the main page on phpbuilder.com for example, you would use "www.phpbuilder.com" as the host and "/" as the page. If you wanted to get the articles section, you woudl use "www.phpbuilder.com" as the host, and "/columns/" as the page.

Hope this helps you out,

I don't believe you can do this with fopen. You could do it with sockets. That shouldn't be too difficult if you know what you're doing. Just send the User-Agent header to whatever you want.
Sockets: http://us2.php.net/manual/en/ref.sockets.php

There's also php class called Snoopy which might make it a little easier. I'm sure there are also other functions and classes which will allow the same.

Have a look at the HTTP class by Manuel Lemos at http://www.phpclasses.org/browse.html/package/3.html

In it, simply use the foll:

       if($error=="")
       {
        $error=$http_connection->SendRequest(array(
         "RequestURI"=>$query,
         "Headers"=>array(
          "Host"=>"www.yourserver.com",
          "User-Agent"=>"PHP Browser",
          "Pragma"=>"no-cache"
