Are there any specific debugging techniques or tools that can help identify and resolve issues related to JSON data manipulation in PHP functions?

One common issue when manipulating JSON data in PHP functions is encountering errors due to incorrect JSON formatting or unexpected data types. To resolve this, you can use the `json_last_error()` function to check for any JSON errors and `json_last_error_msg()` to get a descriptive error message. Additionally, you can use `json_encode()` and `json_decode()` functions with the `JSON_THROW_ON_ERROR` flag to handle exceptions when encoding or decoding JSON data. 

// Example of using json_last_error() and json_last_error_msg() to handle JSON errors
$jsonData = '{"name": "John", "age": 30}';
$decodedData = json_decode($jsonData);

if (json_last_error() !== JSON_ERROR_NONE) {
    echo "JSON decoding error: " . json_last_error_msg();
}

// Example of using JSON_THROW_ON_ERROR flag with json_encode() and json_decode()
try {
    $jsonData = '{"name": "John", "age": 30}';
    $decodedData = json_decode($jsonData, true, 512, JSON_THROW_ON_ERROR);
} catch (JsonException $e) {
    echo "JSON decoding error: " . $e->getMessage();
}
