commandline commands don't work on XP?

goldeneye

I need to call another program that connects to an webserver and gets a webpage, as that server need the agent to be InternetExplorer [ i.e. "Mozilla/4.0 (compatible; MSIE 4.0; Windows NT)" ]. now when I try to execute it ( exec(), system(), backticks ) whatever i try it hangs, but doesn't start download. but it is in the Processes (both cmd.exe and the other prog) and when killing cmd, script continous normally, but without having downloaded the data. when executing the same command from commandline, it works. something i noticed is that the user running the program is the SYSTEM when started from PHP and my name when I enter it in commandline... is there perhaps a way to have php execute the command as me?

or what would be even better, is there a way to define the agent php auths with when connecting to a http server?

You can use lower level functions to connect to the other web server, i.e. fsockopen(), and send HTTP headers yourself. By doing that, you can send the HTTP header that defines the User Agent and lie that you're IE.

already thought of something like that, but i've no idea what headers to send then :/
but thx, now when i know this could work, i'll look for how to do that 🙂 but of course i wouldn't mind if anyone writes here where to find info about that or how that would look like 🙂

The HTTP protocol is gonna look like this, roughly:

GET /the/page.html\n
<headers>\n
\n

and after the \n\n the web server will send the content. Where it says <headers>, you can add the User Agent header. I forgot what it was, but it might be
HTTP-User-Agent: Internet Explorer [Mozilla etc]

HTH,

thx, got it to work now

<?
$fp = fsockopen("$host", 80, &$errno, &$errstr, 60);
if (!$fp) {
echo "$errstr ($errno)<br>\n";
} else {
fputs ($fp, "GET /$url HTTP/1.0\r\nUser-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)\r\n\r\n");
while (!feof($fp)) {
echo fgets($fp,128);
}
fclose($fp);
}
?>

if anyone is intrested in that
