Listar todas las llaves de los elementos de un JSON convertido en array

Últimamente estoy trabajando con formato JSON.

A veces con mucha información. Por ejemplo para PageSpeed Insights, el json contiene 7,102 datos.

Para utilizar la información, la paso a un array, y entonces trabajo con los datos.

Pero cuando la información es extensa, se complica armar la llave que necesitas para acceder cierto dato. Por ejemplo para obtener  el score de las audits que se hacen, el path completo del array sería:

r['lighthouseResult']['categories']['performance']['score']

Y para obtener las auditorías:

r['lighthouseResult']['categories']['performance']['auditRefs']*(56)

el (56) indica que tiene 56 «sub llaves». Y cada sub llave puede tener a su vez sub llaves. El número solo indica las sub llaves en un primer nivel.

Les dejo el código:

function map_json (string $s, mixed $json){
    if (is_string($json)) {
        $a = json_decode($json, true);
    } else {
        $a = $json;
    }
    $all_keys = array();
    $base = '';
    foreach ($a as $key => $value) {
        $base = $s."['$key']";
        if (is_array($value)) {
            $all_keys[] = $base  . '*' . '(' . count($value) . ')';
            $all_keys = array_merge($all_keys, map_json($base,json_encode($value)));
        }else{
            $all_keys[] = $base;
        }
    }
    return $all_keys;
}

Y les dejo una sección del resultado:

r['lighthouseResult']['categories']['performance']*(4)
