curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
Here is the whole script :
$data = "AccountID=xxxxxx&PassPhrase=xxxxxxx&Payee_Account=xxxxxx&Amount=0.01&Memo=theMemo&PAY_IN=1&WORTH_OF=Gold&IGNORE_RATE_CHANGE=y";
$ch = curl_init("https://www.e-gold.com/acct/confirm.asp");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_exec($ch);
curl_close($ch);
If you are trying to make a POST ot GET on the main page - http://www.e-gold.com, there is nothing to do with HTTPS.
Thanks for all your help !!!
