从数组中检索，简单的php

Question

I have this:

print_r($response["member"]);

I need to retrieve name under levels, it's at the bottom, how should I write it: I thought of $response["member"][0]["Sequential"]["levels"]...? Also this number under levels wont be always the same.

Thank you!

An answer might be to use array_walk_recursive by following the official documentation: http://www.php.net/manual/en/function.array-walk-recursive.php

<?php

$properties = new stdClass();
$properties->names = [];
function extractNames($levels, $key, $properties) {
    if (
        is_object($levels) &&
        array_key_exists('Name', get_object_vars($levels)) &&
        array_key_exists('Level_ID', get_object_vars($levels))
    ) {
        $properties->names[] = $levels->Name;
    }
}
array_walk_recursive($response, 'extractNames', $properties);
echo print_r($properties, true);
