Converting a Mysql Result Object to Associative Array (CodeIgniter) - php

Question

I'm trying to get a database query which is an object converted to an associative array, so that I can use it in the calendar class in codeigniter.
This is my model:
<?php
class Get_diary_model extends Model {
function getAllDiaries($year,$month) {
$data = $this->db->query("SELECT day AND entry FROM diary WHERE month=$month AND year=$year"); // the entries for the relevant month and year
foreach($data->result_array() as $row) { // return result as assoc array to use in calendar
echo $row['day'];
echo $row['entry'];
}
return $data;
}
}
and this is the error I get:
atal error: Cannot use object of type CI_DB_mysql_result as array in C:\wamp\www\mm\system\libraries\Calendar.php on line 219
Any ideas?

Check ou this video tutorial, it will help you -> http://net.tutsplus.com/tutorials/php/codeigniter-from-scratch-the-calendar-library/
Your model should look like this:
function getAllDiaries($year,$month)
{
$q = $this->db->query("SELECT day AND entry FROM diary WHERE month=$month AND year=$year");
if($q->num_rows() > 0):
foreach($q->result() as $row):
$data[] = $row;
endforeach;
return $data;
else:
return false;
endif;
}
and your controller:
function index($year = null, $month = null)
{
$this->load->model('Get_diary_model');
if (!$year) {
$year = date('Y');
}
if (!$month) {
$month = date('m');
}
$data['calendar'] = $this->Get_diary_model->getAllDiaries($year, $month);
}

Answer 2

The problem was not in your use of result_array(), more that you later return $data directly. $query = $this->db->query() then use $query->result_array() in the foreach. Then you can return $data after building it up in the foreach.
The other answer is a long-winded way of writing the following:
function getAllDiaries($year,$month)
{
$sql = "SELECT day AND entry FROM diary WHERE month=$month AND year=$year";
return $this->db->query($sql)->result();
}
But of course that will return an array of objects, not an multidimensional array.

Answer 3

Use below simple method,
$query = $this->db->get_where('table', array('table_id' => $id));
$queryArr = $query->result();
foreach ($queryArr[0] as $key=>$val)
{
$row[$key]=$val;
}
print_r($row); //this will give associative array

Answer 4

Here is the solution for CodeIgniter-3
function getAllDiaries(){
$query = $this->db->query("YOUR QUERY HERE");
return $query->result('array');
}
OR
function getAllDiaries(){
return $this->db->query("YOUR QUERY HERE")->result('array');
}
Note: result() function accept "array" or "object" as parameter. Default is "object"
