Codeigniter extract Object std class and create array - php

Question

The question might be silly. But I am stucked in here. :( I am getting all of my database value as an object in controller.
This is how I am fetching database value:
$points = $this->CI->modelgraph->get($user_id);
It is getting all of the data corresponding to that user. This is my sample database table from where I am fetching data:
id user_id b_value h_value date r_value
1 24 330 6.2 10.11.2014 90
2 25 334 6.2 10.11.2014 92
This is static data, phpgraphlib provide in the tutorial.
$data = array("1" => .0032, "2" => .0028, "3" => .0021, "4" => .0033,
"5" => .0034, "6" => .0031, "7" => .0036, "8" => .0027, "9" => .0024,
"10" => .0021, "11" => .0026, "12" => .0024, "13" => .0036,
"14" => .0028, "15" => .0025);
I need to extract the fetched data in this manner:
$data = array("h_value" => b_value,);
How could achieve this? What will be the logic? Any help would be really appreciable.
Here is my approach.. but also not complete.. What I am doing wrong?
$total=count($points);
$i=1;
$dataArray=array();
while($i <= $total) {
foreach($points as $value) {
//echo $value -> h_value;
$field = $value -> h_value;
$labels = $value -> b_value;
$dataArray[$i][$field ] = $labels;
$i++;
}
}
When I var_dump($dataArray); Its giving me this output:
array(11) { [1]=> array(1) { ["6.6"]=> string(3) "358" } [2]=> array(1) { ["7.4"]=> string(3) "201" } [3]=> array(1) { ["6.5"]=> string(3) "144" } [4]=> array(1) { ["6.5"]=> string(3) "112" } [5]=> array(1) { ["6.2"]=> string(3) "144" } [6]=> array(1) { ["6.2"]=> string(3) "185" } [7]=> array(1) { ["7.0"]=> string(3) "176" } [8]=> array(1) { ["7.5"]=> string(3) "234" } [9]=> array(1) { ["6.5"]=> string(3) "365" } [10]=> array(1) { ["6.2"]=> string(3) "110" } [11]=> array(1) { ["4.2"]=> string(3) "100" } }
But When I var_dump($data); Its giving this:
array(15) { [1]=> float(0.0032) [2]=> float(0.0028) [3]=> float(0.0021) [4]=> float(0.0033) [5]=> float(0.0034) [6]=> float(0.0031) [7]=> float(0.0036) [8]=> float(0.0027) [9]=> float(0.0024) [10]=> float(0.0021) [11]=> float(0.0026) [12]=> float(0.0024) [13]=> float(0.0036) [14]=> float(0.0028) [15]=> float(0.0025) }
Its clearly visible I have messed up . Where is the wrong ?
Here is the output I print_r($points); Its giving this:
Array ( [0] => stdClass Object ( [id] => 12 [user_id] => 24 [b_value] => 358 [h_value] => 6.6 [rec_date] => 2014-09-19 [rec_time] => [h_value] => 1[date_added] => 2012-09-19 16:38:05 [date_modified] => 0000-00-00 00:00:00 ) [1] ..........

Answer 1

Please see below code.
It is self-explanatory.
Replace your values accordingly.
<?php
function modelFunction($user_id) {
$this->db->select('h_value, b_value');
$this->db->from('YOUR_TABLE_NAME');
$this->db->where('user_id', $user_id);
$query = $this->db->get();
$arr = array();
if ($query->num_rows()) {
$i=0;
foreach ($query->result_array() as $row) {
extract($row);
$arr[$i][$h_value] = $b_value;
++$i;
}
}
}
?>
Controller:
<?php
$points = $this->CI->modelFunction->get($user_id);
?>
Answer edited as per OP's request:
<?php
$dataArray = array();
for ($i=0 ; $i<= $total ; $i++) {
$value = $points[$i];
$field = $value->h_value;
$labels = $value->b_value;
$dataArray[$i][$field ] = $labels;
$i++;
}
?>

Answer 2

$new_array = array();
foreach($points as $point){
$new_array[] = array(
'id' => $point->id,
'user_id' => $point->user_id
);
}

Answer 3

Nice little helper function:
function object_to_array($data)
{
if (is_object($data)) {
$data = get_object_vars($data);
}
if (is_array($data)) {
return array_map(__FUNCTION__, $data);
}
else {
return $data;
}
}
example usage:
$data['points'] = $this->CI->modelgraph->get($user_id);
$data['points'] = object_to_array($data['points']);
