Are there any PHP libraries or tools specifically designed to work with complex JSON data structures like Mehrdimensionale Arrays?

Working with complex JSON data structures like multidimensional arrays in PHP can be challenging and error-prone without the right tools or libraries. One way to handle this is by using libraries such as `json_decode` and `json_encode` in PHP to easily convert JSON data to PHP arrays and vice versa. Additionally, the `array_merge_recursive` function can be used to merge multidimensional arrays in PHP.

// Example of decoding JSON data into a multidimensional array
$jsonData = '{"name": "John", "age": 30, "children": [{"name": "Alice", "age": 5}, {"name": "Bob", "age": 8}]}';
$arrayData = json_decode($jsonData, true);

// Example of encoding a multidimensional array into JSON data
$multiArray = array("name" => "John", "age" => 30, "children" => array(array("name" => "Alice", "age" => 5), array("name" => "Bob", "age" => 8)));
$jsonData = json_encode($multiArray);

// Example of merging two multidimensional arrays
$array1 = array("name" => "John", "age" => 30, "children" => array("Alice", "Bob"));
$array2 = array("children" => array("Charlie", "David"));
$mergedArray = array_merge_recursive($array1, $array2);
