filling out forms through proxies with php

[zelnaga]

i'm connecting to the internet via a proxy, and am having problems
filling out forms... below is the code i have, and below that is the
http request i am trying to make it look like. they look the same to
me, but it isn't working, so i guess they aren't...

$proxy = fsockopen("tcp://someaddresshere", 80, $errno,
$errstr);
$temp = "somethingelse=blablabla";
fputs($proxy,"GET somesite HTTP/1.0\r\n");
fputs($proxy,"Accept: */*\r\n");
fputs($proxy,"Referer: http://someothersitesite\r\n");
fputs($proxy,"Content-Type:
application/x-www-form-urlencoded\r\n");
fputs($proxy,"Content-Length: " . strlen($temp) . "\r\n\r\n");
fputs($proxy,$temp . "\r\n");
while (!feof($proxy))
print fgets($proxy);
fclose($proxy);

with that script, i don't get anything. however, with this http
request, from opera 7.10, i do:
