Are there any specific PHP functions or methods that can help in organizing strings into a nested array structure?

To organize strings into a nested array structure in PHP, you can use functions like `explode()` to split the string into an array based on a delimiter, and then iterate through the array to build the nested structure as needed. Additionally, you can use functions like `array_push()` or `[]` notation to add elements to the nested arrays. 

$string = "parent.child.grandchild";
$keys = explode(".", $string);

$result = [];
$current = &$result;

foreach ($keys as $key) {
    $current[$key] = [];
    $current = &$current[$key];
}

print_r($result);
