I have an array of objects, and i want to sum value of one of the property.Here is a picture which will show the structre of array.
Here is my code,that doesn't work.
print_r($res);//this appear the structure of array,which i will show.
$sum = 0;
foreach($res as $key=>$value){
if(isset($value->sent))
$sum += $value->sent;
}
echo $sum;
Make use of array_reduce function like below
$sum = array_reduce($res->intervalStats, function($i, $obj)
{
return $i += $obj->spent;
});
echo $sum;
Sample Test
[akshay@localhost tmp]$ cat test.php
<?php
$res = (object)array( "intervalStats" => array( (object)array("spent"=>1),(object)array("spent"=>5) ) );
$sum = array_reduce($res->intervalStats, function($i, $obj)
{
return $i += $obj->spent;
});
// Input
print_r($res);
// Output
echo $sum;
?>
Output
[akshay@localhost tmp]$ php test.php
stdClass Object
(
[intervalStats] => Array
(
[0] => stdClass Object
(
[spent] => 1
)
[1] => stdClass Object
(
[spent] => 5
)
)
)

$sum = 0;
$result=$res->intervalStats;
foreach($result as $key=>$value){
if(isset($value->spent))
$sum += $value->spent;
}
echo $sum;
This is working on lates PHP versions (tested on 7.2)
$sum = array_sum(array_column($res->intervalStats, 'spent'));
$res->intervalStats.->sent? maybe you meant->spent
