Tente usar isso, conforme necessário,
program valores da coluna:<?php
$pdo = Database::connect();
$sql="SELECT t1.*, t2.*
FROM form_fields t1, user_choices t2
WHERE t1.field_name = t2.field_name
and group_id=1 and user_id=".$_SESSION['user_id']." ";
//$result = $pdo->query($sql);
echo '<select class="form-control" name="program">';
foreach ($pdo->query($sql) as $row_program){
$options = $row_program['program'];// as you need this column values
$optionsArr = explode(",", $options);
foreach ($optionsArr as $key=>$row){
echo '<option value='.$row[$key].'>'.$row[$key].'</option>';
}
}
echo '</select>';
?>
