How to get values from an array, inside another array, with stdClass Objects?-CodePudding

I'm trying to get the values from [iso_3166_1] and [title] in an array, which is inside another array.

I have searched and tried several solutions and tips, but none of them works, and now I'm stuck.

The content is fetched like this

$content = json_decode($jsonFile);

Then I have the following content

stdClass Object (
    [id] => 508947 [titles] => Array (
         [0] => stdClass Object ( [iso_3166_1] => FR [title] => Devenir rouge [type] => )
         [1] => stdClass Object ( [iso_3166_1] => MX [title] => Red [type] => )
         [2] => stdClass Object ( [iso_3166_1] => LV [title] => Es sarkstu [type] => )
         [3] => stdClass Object ( [iso_3166_1] => NO [title] => Rød [type] => )
         [4] => stdClass Object ( [iso_3166_1] => SE [title] => Röd [type] => )
         [5] => stdClass Object ( [iso_3166_1] => PE [title] => Red [type] => )
    )
)

I have tried to make a foreach loop like this for instance, but that only gives me Warning: Invalid argument supplied for foreach():

foreach($content as $row) {
    foreach($row['titles'] as $country) {
        echo $country['iso_3166_1']['title'];
   }
}

I have also tried tho following, to try get rid of the stdClass Objects in the array, which does not seem to work either:

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

CodePudding user response：

this should work for you to compare & understand why your code fails.

$titles = $content->titles;

foreach ($titles as $country_instance) {
    echo $country_instance->iso_3166_1;
    echo '-';
    echo $country_instance->title;
    echo '<br>';
}

CodePudding user response：

If I understand the question right, json_decode associative mode should return arrays of arrays from your JSON.

$array = json_decode($json, true);

You can also try using flag JSON_OBJECT_AS_ARRAY but from what I've read it only does something when null is supplied as the second argument.
