Answer 1

2 solutions

// multiple queries
$stmt = $pdo->prepare('INSERT INTO table SET memberID=:memberID, programID=:programID, date_added=NOW()');
$data = array(155, 165, 175, 185);
foreach($data as $d) {
    $stmt->execute(array(':memberID' => $memberid, ':programID' => $d));
}

And

// one query
$data = array(155, 165, 175, 185);
$values = array();
foreach($data as $d) {
    $values[] = sprintf('(%d, %d, NOW())', $d, $memberid);
}
$sql = sprintf('INSERT INTO table (memberID, programID, date_added) VALUES %s', implode (', ', $values));
$pdo->exec($sql);
