Count objects in an array (php)

Question

I'm a complete newbie at php, but anyway, here it goes:

I want to count the amount of ["completed"]=> bool(true) in the array below.

I was able to count the total by doing this: $totalCount = count($object->data);. Do I need to do a foreach() in order to get the amount of completed ones or can I get around it by just doing some kind of count()?

Thanks!

object(stdClass)#2 (1) {
  ["data"]=>
  array(232) {
    [0]=>
    object(stdClass)#3 (2) {
      ["id"]=>
      int(13081073106396)
      ["completed"]=>
      bool(true)
    }
    [1]=>
    object(stdClass)#4 (2) {
      ["id"]=>
      int(13160080793822)
      ["completed"]=>
      bool(false)
    }

You can use the answer that @gratz is referring to, just remember to reference object properties with the -> operator, so it is $obj->data and not $obj['data'] because you are dealing with objects and not arrays. — EJTH

I think something like that might work:

var $count = 0;
foreach($stdClass->data as $obj)
    if($obj->completed)
        $count++;

Consider $oObject is your object

$array = json_decode(json_encode($oObject),true);

then apply simple array count like

echo count($array);

It will return total count of data. Hope this will help!

Use a callback to count:

$countCompleted = 0;

array_map(function ($n) use $countCompleted {
    if ( $n->completed === true )
         $countCompleted ++;
}, $objectMap->data );
