Retrieve only one row of comment - php

Question

I have a site developed in codeigniter where I want to retrieve comment of a specific tee.
I have a table tee like that:
- id
- user_id
- name
- created
- modified
And the table tee_comments like that:
- id
- user_id
- tee_id
- created
- modified
I have done this query:
$this->db->select('*,tee.id as id,tee.created as created, tee_comments.id as tee_comments_id, tee_comments.created as tee_comments_created, tee_comments.modified as tee_comments_modified');
$this->db->from('tee');
$this->db->join('tee_comments', 'tee_comments.tee_id = tee.id','left outer');
$this->db->order_by("tee.created", "desc");
$query = $this->db->get();
With this query I retrieve two rows of tee because I have two comments in that tee.
My goal is to retrieve only one row where inside there is an array of comment like:
tee{
id,
name,
created,
modified
comment{
[0]
id,
tee_id,
comment,
created,
modified
[1]
id,
tee_id,
comment,
created,
modified
}
}
I have tried into the join:
- left
- right
- left outer
- right outer
But doesn't solve the problem, is there a way to do that?
Thanks

I love CodeIgniter! I use it constantly! You have 2 really simple options here:
One way would be to use limit.
$this->db->select('*,tee.id as id,tee.created as created, tee_comments.id as tee_comments_id, tee_comments.created as tee_comments_created, tee_comments.modified as tee_comments_modified');
$this->db->join('tee_comments', 'tee_comments.tee_id = tee.id','left outer');
$this->db->order_by("tee.created", "desc");
$query = $this->db->limit(1)->get('tee');
Another way is to get first item in results Array
$query = $this->db->get();
$results = $query->result(); // gets return as an array
$row = $results[0]; // will be first row in results array
Keep in mind tho, $row will return as a object(stdClass) meaning you'll have to retrieve things from it like $row->column_name.
A handy little snippet I like to use after a call is below. It makes the row Object's Array's instead.
$results = $db->get('tee')->result(); // snippet comes after you have result array
// snippet here
foreach ($r as $k => $v) { $results[$k] = array(); foreach ($v as $kk => $vv) { $results[$k][$kk] = $vv != "NULL" ? trim($vv) : ""; } }

Answer 2

Use $this->db->limit(1) to retrieve a single record.
According to the accepted answer on this question, you may need to put the limit statement before the select:
$this->db->limit(1);
$this->db->select('*,tee.id as id,tee.created as created, tee_comments.id as tee_comments_id, tee_comments.created as tee_comments_created, tee_comments.modified as tee_comments_modified');
$this->db->from('tee');

Option one:
for ($i = 0; $i < count($records); $i++)
{
$data = $records[$i];
// work with date.
if($i == 1)
break;
}
Option two:
just assign the first row to var.
$row = $records['tee']['comment'][0];
