[SOLVED] Foreach with implode comma

Please i'm stucked with this problem for an hour now(yeah i'm newbie in this).

this is a piece of code in my controller

PHP Code:

$tags = $this->input->post('check_list');
            
            
            foreach($tags as $t){
                
                $q = $this->db->get_where('info', array('text_id' => $t))->result()->text_name;
                //$data['q'] = $this->db->get_where('info', array('text_id' => $t))->result()->text_name;
                
                $data['qe'] = $q.' ,';
            } 


and this is the view(index.php). i also wanted to see the query i did,so tried to output it with last_query() :

PHP Code:

<?php
    echo form_open();
    ?>

<input type="checkbox" name="check_list[]" value="1">love<br>
<input type="checkbox" name="check_list[]" value="2">heart<br>
<input type="checkbox" name="check_list[]" value="3">heaven<br>
<input type="checkbox" name="check_list[]" value="4">sun<br>
<input type="checkbox" name="check_list[]" value="5">earth<br>
    
        <?php
    echo form_submit('', 'Save');
    echo form_close();
    ?>
    
    <div>The Checked boxes names were: 

<?php echo $qe;
    ?></div>
     


and the printed result is:

Code:

,string(2) " ," string(4) "SELECT * FROM `info` WHERE `text_id` = '4'"

what i want to achieve is something like this depending on the selected checbox by their id:
The Checked boxes names were: sun, heaven, earth

UPDATE(8/6/2016 11:57pm)
Here is the fix:

PHP Code:

//in controller
$tags = $this->input->post('check_list');
       if (isset($tags)){
        $q = [];
             
            
            foreach($tags as $t){
                
                $q[] = $this->db->get_where('info', array('text_id' => $t))->result()->text_name;
                
            } 
}

$data['qe'] = immplode(', ', $q);

//inside view

 echo $qe; // prints Love, Sun, Heaven (when their ids are being selected)
