GROUP and COUNT() multiple fields in CakePHP - mysql

Question

This is my database:
week, subbizname, devicetype
20141203, common, PC
20141203, unknown, PC
20141210, KRsinKD, SP
20141210, unknown, PC
20141217, Unknown, SP
20141217, Chintai, TAB
....
I am trying to get the number of records for each unique couple devicetype/week.
Ex:
array(
20141203 => array(
'PC'=>2,
'TAB'=>0,
'SP'=>0
),
20141210 => array(
'PC'=>1,
'TAB'=>0,
'SP'=>1
),
...
.....
)
UPDATE:
I have used query:
$data = $this->Test->find('all', array(
'conditions'=>array(
'OR'=>array(
array('devicetype'=>'PC'),
array('devicetype'=>'SP'),
array('devicetype'=>'TAB'),
)
),
'fields'=>"devicetype,week,COUNT(devicetype) AS countDevice",
'group'=>"week,devicetype"
));
Thing is, it returns something like this:
(int) 0 => array(
'Test' => array(
'devicetype' => 'PC',
'week' => '20141126'
),
(int) 0 => array(
'countDevice' => '34844'
)
),
(int) 1 => array(
'Test' => array(
'devicetype' => 'SP',
'week' => '20141126'
),
(int) 0 => array(
'countDevice' => '32401'
)
),
(int) 2 => array(
'Test' => array(
'devicetype' => 'TAB',
'week' => '20141126'
),
(int) 0 => array(
'countDevice' => '4256'
)
),
(int) 3 => array(
'Test' => array(
'devicetype' => 'PC',
'week' => '20141203'
),
(int) 0 => array(
'countDevice' => '96564'
)
),
(int) 4 => array(
'Test' => array(
'devicetype' => 'SP',
'week' => '20141203'
),
(int) 0 => array(
'countDevice' => '97450'
)
),
But I do not manage to get the expected result.
Surely there must be a better way.
How can I fix this?

Using your $data variable, you can do:
$d = array();
foreach ($data as $value) {
$week = $value['Test']['week'];
if (isset($d[$week])) {
$d[$week][$value['Test']['devicetype']] = $value[0]['countDevice'];
} else {
$d[$week] = array($value['Test']['devicetype'] => $value[0]['countDevice']);
}
}
print_r($d); // $d will contain the data in your required format
