Question

How can I find the maximum value for the objects in my array?

Say I have an array of objects like this:

$data_points = [$point1, $po         


        

Answer 1

try this:

$point1 = new stdClass;
$point1->value = 0.2;
$point1->name = 'Bob';

$point2 = new stdClass;
$point2->value = 1.2;
$point2->name = 'Dave';

$point3 = new stdClass;
$point3->value = 0.8;
$point3->name = 'Steve';

$data_points = [$point1, $point2, $point3];

function max_attribute_in_array($data_points, $value='value'){
    $max=0;
    foreach($data_points as $point){
        if($max < (float)$point->{$value}){
            $max = $point->{$value};
        }
    }
    return $max;
}
$max = max_attribute_in_array($data_points);
var_dump($max);

response:

float 1.2
