foreach loop repeating same value - codeigniter

Question

I am getting result from two table in my database. Table one has Project name and table two has sub project names under project name this two table is connected by a id.
Now when I output result using foreach by joining two table it is showing showing project name repeatedly as there are more than one subproject under that repeated project.
I want that the project name will be single and subproject result will loop under the main project name. How to do that?
I amusing codeigniter for development.
my view page:
<?php foreach ($reportlist as $project_item): { ?>
<tr>
<td>
<form method='post' action='update_project'>
<input type='hidden' value='<?php echo ($project_item['pid']); ?>' name='pid'>
<input type='hidden' value='<?php echo $project_item['pp_id']; ?>' name='pp_id'>
<input type="submit" class="linkButton" value="<?php echo $project_item['p_name'] ?>">
</form>
</td>
<td>
<form method='post' action='update_subproject'>
<input type='hidden' value='<?php echo $project_item['pid']; ?>' name='pid'>
<input type='hidden' value='<?php echo $project_item['pp_id']; ?>' name='pp_id'>
<input type="submit" class="linkButton" value="<?php echo $project_item['component_name'] ?>" >
</form>
</td>
<td><?php echo $project_item['coordinating_authority'] ?></td>
<td><?php echo $project_item['start_month'] ?></td>
<td><?php echo $project_item['target_month'] ?></td>
<td><?php echo $project_item['stat_pro'] ?></td>
<td><?php echo $project_item['stat_pro'] ?></td>
<td><?php echo $project_item['remark_pro'] ?></td>
</tr>
<?php } endforeach ?>
</tbody>
My cotroller page:
$this->load->model('projsubproj_add_model');
$data['reportlist'] = $this->projsubproj_add_model->existing_project();
$this->load->view('PAGE-DESIGN/adminheader');
$this->load->view('existing_project_view', $data);
$this->load->view('PAGE-DESIGN/footer');
and my model:
public function existing_project()
{
{
$this->db->select('project_tab.p_name,
pp_project_tab.pp_id AS pp_id,
pp_project_tab.pid AS pid,
pp_project_tab.ppname AS component_name,
pp_project_tab.pp_smonth AS start_month,
pp_project_tab.pp_emonth AS target_month,
pp_project_tab.pp_cordn_reqrd AS coordinating_authority,
pp_project_tab.pps_status AS stat_pro,
pp_project_tab.remarks AS remark_pro');
$this->db->from('project_tab');
$this->db->join('pp_project_tab', 'pp_project_tab.pid =project_tab.pid');
//$this->db->join('pp_status_tab', 'pp_status_tab.pp_id = pp_project_tab.pp_id');
$this->db->order_by('ppname', 'desc');
$query = $this->db->get();
return $query->result_array();
}
$query = $this->db->get_where('project_tab');
return $query->row_array();
}

I got the solution: I just edited my view file for through foreach loop. I made two function to to extract results from two tables and joined them with condition that if the pid of subproject table matches with the pid of subject table, then echo subproject name and its components inside foreach loop of Project loop.
Here is my code:
$projects is for extracting data from project_tab,
$components is for extracting data from pp_project_tab
<?php
foreach ($projects as $project) {
echo $project['p_name'];
foreach ($components as $component) {
if ($project['pid']==$component['pid']) {
echo $component['ppname'] ;
}
}
}
?>
