Certainly.  It's a function in my class.SalesForceAPI.php:

Code:

function importContacts( $data, $mapping )
{
 // format mapping for SilverPop -> SalesForce
 $mapping = array_flip( $mapping );
 
 // separate header row
 $header = $data[0];
 $data = array_slice( $data, 1 );
 
 // initialize contacts array
 $contacts = array();
 $externalID = "Id";
 
 // build contact classes
 foreach( $data as $record )
 {
  $contact = new stdclass();
  $contact->type = 'Contact';
  
  // process contact mapped fields
  $fields = array();
  for( $i = 0; $i < count( $header ); $i++ )
  {
   if( !empty( $record[$i] ) && array_key_exists( $header[$i], $mapping ) )
   {
    $field = $mapping[$header[$i]];
    $fields[$field] = $this->prepare( $record[$i] );
    if( $field == $externalID )
     $contact->$field = $this->prepare( $record[$i] );
   }
  }
  $contact->fields = $fields;
  $contacts[] = $contact;
 }
 
 // upsert data (update/insert)
 $upsertResult = $this->api->upsert( $externalID, $contacts );

 return $upsertResult;
}

 
The function takes two inputs:

1) $data is a two-dimensional array version of a CSV file.  The first row contains headers, the second, third, fourth, etc. rows contain values.

2) $mapping is a one-dimensional array that maps SalesForce field names to the header names in the data file.  The first operation in the function flips the keys/values so it's the header names mapping to the SalesForce field names.

Code:

// SalesForce field name => SilverPop field name
$mapping = array(
  "Id"
   => "SalesForce ID",
  "Email"
   => "EMAIL",
  "LastName"
   => "Last Name",
  "FirstName"
   => "First Name"
 );

After running the function on a data file with a single record, I get an array of stdclass objects that looks like this:

Code:

Array
(
    [0] => stdClass Object
        (
            [type] => Contact
            [Id] => 00300000004NL8rAAG
            [fields] => Array
                (
                    [FirstName] => Anton
                    [LastName] => Venema
                    [Phone] => (604) 628-5224
                    [Id] => 00300000004NL8rAAG
                )

        )

)
