How to upload and import a lot of people at once

import.php

<?
 
// Load the PHP API library.
require_once 'streamsend-php/src/streamsend.php';
 
// Replace these with your actual API Login ID (username) and Key (password).
// Refer to http://app.streamsend.com/docs/api/index.html for more information.
define('STREAMSEND_USERNAME', 'abc');
define('STREAMSEND_PASSWORD', '123');
 
// Fetch your audience. (You only have one.)
$audience = SSAudience::find('first');
 
// Initialize a new file upload.  Customize the filename to point to the full
// local path of your comma- or tab-delimited data file.
$upload = new SSUpload(array('filename' => dirname(__FILE__) . '/test.csv'));

// Create the upload object.  This triggers the uploading of the file to 
// StreamSend.
//
// NOTE: Because this could take a while, it should ideally be done separately
// from the user interface so that your users don't have to wait for it.
$upload->save();

// Initialize a new import using the upload you just created.  Please refer
// to the full API documentation for information on what all the available
// attributes are and their possible values.
$import = new SSImport(array(
    'audience_id' => $audience->id(),
    'columns' => array(
        'email_address',
        2,
        12
    ),
    'upload_id' => $upload->id(),
    'separator' => 'Comma',
    'reactivate' => 'false',
    'skip_blank_columns' => 'false',
    'ignore_first_row' => 'false'
));

// Create the import, thereby triggering the import process.
$import->save();

// NOTE: Your people have not been added yet!  Successful creation
// of an import object only means that import has *started*.  Since
// this process can take upwards of many minutes (depending on the
// size of the file and the size of your audience) the actual
// import is done separately from creation so that your script is
// not forced to wait for it to complete.
//
// If you need to know when the import is complete, you will need to
// poll the API for its status at a regular interval.  This is as
// simple as reloading the object every so often until the import is
// complete.  Again, because this may take some time, it too should
// be done in a background process detached from the user interface.
do
{
    sleep(10); // seconds
    $import->reload();
}
while ($import->pending());
