Count Items in Array PHP

Question

I'm having trouble counting my arrays how someone can help.

Array
(
 [2014年06月17日] => Array
 (
 [0] => Array
 (
 [id] => 40404
 [client] => Client 1
 [date] => 2014年06月17日T14:57:08+0100
 )
 [1] => Array
 (
 [id] => 40403
 [client] => Client 1
 [date] => 2014年06月17日T14:39:02+0100
 )
 [2] => Array
 (
 [id] => 40402
 [client] => Client 2
 [date] => 2014年06月17日T13:34:18+0100
 )
 )
)

I would like filter this array after I created it to look like this.

Array
(
 [2014年06月17日] => Array
 (
 [Client 1] => Array
 (
 [submitted] => 2
 )
 [Client 2] => Array
 (
 [submitted] => 1
 )
)

Currently my code looks like this, i'm guessing I need another foreach to filter this more but i'm stuck filting this array.

 foreach ($submissions as $sortArray) {
 $dataJson[substr($sortArray['thing']['created'], 0, 10)][] = array(
 'id' => $sortArray['id'],
 'client' => $sortArray['thing']['client']['name'],
 'date' => $sortArray['thing']['created']
 );
 $filterd = $dataJson;
 }
 echo "<pre>";
 print_r($filterd);
 echo "</pre>";

Something like this

$result = array();
foreach($source as $day => $orders) {
 $clients = array();
 foreach ($orders as $order) {
 if (!isset($clients[$order['client']])) {
 $clients[$order['client']] = array('submitted' => 1);
 }
 else {
 $clients[$order['client']]['submitted']++;
 }
 }
 $result[$day] = $clients;
}

You can just loop and use the client's identifier as an array key:

foreach($submissions as $d)
{
 if(isset($counts[$d['client']]))
 $counts[$d['client']] = 1;
 else
 $counts[$d['client']]+=1;
}

Answer 3

You can do it this way:

 $array = array();
 foreach($submissions as $submission){
 $array[$submission['client']]['submitted'] = isset($array[$submission['client']]['submitted'])? ($array[$submission['client']]['submitted'] + 1): 1;
 }
