Are there any specific functions or methods in PHP that can help extract the last entry from a JSON object?

To extract the last entry from a JSON object in PHP, you can decode the JSON string using `json_decode()` to convert it into an associative array, then use `end()` function to get the last element of the array.

$jsonString = '{"key1": "value1", "key2": "value2", "key3": "value3"}';
$data = json_decode($jsonString, true);

$lastEntry = end($data);
echo json_encode($lastEntry);
