Sending a campaign to a segment - mailchimp

Question

Anyone know how to get a campaign to send to a segment? This code isn't working. It will send an email to all people in the campaign. It will not use the segment. (This is some more text so I can get it to pass the validation of SO.)
My code:
//get member list
$memberArray = $api->listMembers($inStockListId);
foreach ($memberArray['data'] as $member) {
$memberInfo = $api->listMemberInfo($inStockListId, $member['email']);
$_productId = $memberInfo['data'][0]['merges']['PRODUCTID'];
$productId='34';
if ($productId == $_productId) {
array_push($emailArray, $member['email']);
}
}
//create new segment for campaign
$listStaticSegmentId = $api->listStaticSegmentAdd($inStockListId, 'inStockStaticSegment');
//add members to segment
$val = $api->listStaticSegmentMembersAdd($inStockListId, $listStaticSegmentId, $emailArray);
$conditions = array();
$conditions[] = array(
'field' => 'email',
'op' => 'like',
'value' => '%'
);
$segment_options = array(
'match' => 'all',
'conditions' => $conditions
);
$type = 'regular';
$options = array(
'template_id' => $campaignTemplateId,
'list_id' => $inStockListId,
'subject' => 'In-Stock Notification',
'from_email' => 'from#email.com',
'from_name' => 'My From Name'
);
$content = array(
'html_main' => 'some pretty html content',
'html_sidecolumn' => 'this goes in a side column',
'html_header' => 'this gets placed in the header',
'html_footer' => 'the footer with an *|UNSUB|* message',
'text' => 'text content text content *|UNSUB|*'
);
$newCampaignId = $api->campaignCreate($type, $options, $content, $segment_options);

I figured it out. Essentially, here is the flow. If you want detailed code, send me a message and I'll be glad to help.
$api = new MCAPI($this->_apiKey);
$api->listMemberInfo($this->_listId, $member['email']);
$api->listUpdateMember($this->_listId, $member['email'], $mergeVars);
$api->listStaticSegmentDel($this->_listId, $segment['id']);
$api->listStaticSegmentAdd($this->_listId, $segmentName);
$api->listStaticSegmentMembersAdd($this->_listId, $segmentId, $emailArray);
$api->campaignCreate($type, $options, $content, $segment_options);
//$api->campaignSendTest($newCampaignId, array($member['email']));
$api->campaignSendNow($newCampaignId);
Note, this is done via the MailChimp PHP API.
