How can understanding and interpreting error messages in PHP help troubleshoot issues related to JSON data manipulation?

Understanding and interpreting error messages in PHP can help troubleshoot issues related to JSON data manipulation by providing insights into what went wrong during the processing of JSON data. By carefully reading and understanding these error messages, developers can pinpoint the exact cause of the issue and take appropriate corrective actions to resolve it. 

// Example code snippet to demonstrate handling errors during JSON data manipulation
$jsonData = '{"name": "John", "age": 30}';
$decodedData = json_decode($jsonData);

if ($decodedData === null && json_last_error() !== JSON_ERROR_NONE) {
    // Handle JSON decoding error
    echo 'Error decoding JSON data: ' . json_last_error_msg();
} else {
    // Process decoded JSON data
    echo 'Decoded JSON data: ';
    print_r($decodedData);
}
