Как декодировать несколько массивов. в laravel

Question

Я пытался декодировать это

$ids = json_decode($tracks1[0], true); or $ids = json_decode($tracks1, true);

, но не сработало. Может кто-нибудь объяснить, почему не сработало. это.

    Array
    (
        [0] => {"3430":"3430","1279":"1279","4925":"4925","3435":"3435","1899":"1899","1900":"1900","1901":"1901","1905":"1905","3971":"3971","4306":"4306","4962":"4962","4964":"4964"}

Попробуйте это

$json_array = json_decode($tracks1, true);

foreach($json_array as $key => $arrays){
    echo $key . "<br />";
    foreach($arrays as $array){
        foreach($array as $key => $value){
            echo $key . " => " . $value . "<br />";
        }
    }
    echo "<br />";
}
