Hello,
I made a curl which send some data to a url and the result of script should be displayed.
the script looks like this

<?php 

// Initialize curl 
$ch = curl_init(); 


// Get curl to POST 
curl_setopt($ch, CURLOPT_POST, 1); 
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST,0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);

// Instruct curl to suppress the output from Online Mart, and to directly  
// return the transfer instead.  (Output will be stored in $txResult.) 
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, 1 ); 

// This is the location of the Online Mart payment gateway 
 

 //https://www.beanstream.com/scripts/process_transaction.asp
 curl_setopt( $ch, CURLOPT_URL, "https://www.beanstream.com/scripts/process_transaction.asp" ); 
// These are the transaction parameters that we will POST 
 $merchant_id=117489490;

 /*echo curl_setopt( $ch, CURLOPT_POSTFIELDS,"requestType=BACKEND&merchant_id=117489490&trnCardOwner=Paul+Randal&trnCardNumber=4030000010001234&trnExpMonth=01&trnExpYear=05&trnOrderNumber=2232&trnAmount=10.00&ordEmailAddress=prandal@mydomain.net&ordName=Paul+Randal&ordPhoneNumber=9999999&ordAddress1=1045+Main+Street&ordAddress2=&ordCity=Vancouver&ordProvince=BC&ordPostalCode=V8R+1J6&ordCountry=CA&approvedPage=payment_success.php?msg=success&declinedPage=payment_success.php?msg=declined" );*/

curl_setopt( $ch, CURLOPT_POSTFIELDS,$ash); 

// Now POST the transaction.  $txResult will contain Online Mart's response 
$txResult = curl_exec($ch); 

echo "Result:<BR>"; 
echo $txResult; 
curl_close( $ch ); 


?>

It's showing the output as blank , See : http://ashutosh4u.100webspace.net/Hu...a/curl_api.php
Can some one help, need help urgently

It works, i fact.
When I run it from my place, I have an

string(37) "Invalid merchant id (merchant_id = 0)"

when I do a var_dump() of the result.
