I am trying to use curl to send post data from domain A to a php page on
domain B which parses the post information and modifies a user database.

I do not need the html output that curl grabs from the php page on domain B
(as I want the user to stay on domain A), I only need the database to be
modified. I would just do this using php and not cURL, but the php page on
domain B can't be changed right now, so I can't get back to domain A if I
post to domain B.

I can successfully send a request that correctly modifies the database using
the unix command curl, but can't get it to work using php.

Are there differences in the default settings of the two that could be
causing this problem?

Here is my unix command:

curl 'http://www.domainB.com/signup_submit.php' \

-H 'Host: www.domainB.com' \

-H 'User-Agent: Mozilla/5.0 (windows; U; Windows NT 6.0; en-US; v:1.9.0.10)
Gecko/2009042316 Firefox/3.0.10 (.NET CLR 3.5.30729)' \

-H 'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8'
\

-H 'Accept-Language: en-us,en;q=0.5' \

-H 'Accept-Encoding: gzip,deflate' \

-H 'Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7' \

-H 'Keep-Alive: 300' \

-H 'Connection: keep-alive' \

-H 'Referer: http://www.domainB.com/page.html' \

-H 'Content-Type: application/x-www-form-urlencoded' \

-H 'Content-Length: 112' \

-d 'email_address=test210_at_mailinator.com&tracker_id=test210&offer_id=997' \

-o out.html -D header.txt -L

And my php code, which does not result in any database modification:

$url = 'http://www.domainB.com/signup_submit.php';

$data =
'email_address=test210_at_mailinator.com&tracker_id=test210&offer_id=997';

$ch = curl_init();

$header[0] = 'Host: www.domainB.com';

$header[] = 'User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US;
rv:1.9.0.10) Gecko/2009042316 Firefox/3.0.10 (.NET CLR 3.5.30729)';

$header[] = 'Accept:
text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8';

$header[] = 'Accept-Language: en-us,en;q=0.5';

$header[] = 'Accept-Encoding: gzip,deflate';

$header[] = 'Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7';

$header[] = 'Keep-Alive: 300';

$header[] = 'Connection: keep-alive';

$header[] = 'Referer: http://www.domainB.com/page.html';

$header[] = 'Content-Type: application/x-www-form-urlencoded';

$header[] = 'Content-Length: 112';

curl_setopt($ch,CURLOPT_URL,$url);

curl_setopt($ch,CURLOPT_FOLLOWLOCATION, true);

curl_setopt($ch,CURLOPT_POST,true);

curl_setopt($ch,CURLOPT_POSTFIELDS,$data);

curl_setopt($ch,CURLOPT_HTTPHEADER,$header);

curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);

$result = curl_exec($ch);

curl_close($ch);
