如何在foreach之外检索stdobject属性

Question

Array
    (
        [0] => stdClass Object
            (
                [rating] => 2
            )

    )

I'm trying to get like this

foreach ($star_1 as $key) 
        {
            print_r($key->rating);
        }

How do I get the rating value outside the foreach

Answer 1

This value is an array containing elements of type stdClass . These elements have fields that can be accessed using element->field_name . Since you want to access the rating of the first element in your array (= at index 0), you should use

$array[0]->rating
