How can one efficiently troubleshoot errors related to JSON parsing in PHP?

To efficiently troubleshoot errors related to JSON parsing in PHP, one can use the json_last_error() function to check for any errors after decoding a JSON string. This function returns an integer representing the last error that occurred during the decoding process. By checking this error code, one can identify the specific issue and take appropriate action to resolve it. 

$json_string = '{"key": "value"}';

$data = json_decode($json_string);

if ($data === null && json_last_error() !== JSON_ERROR_NONE) {
    // Handle JSON parsing error
    echo 'Error parsing JSON: ' . json_last_error_msg();
} else {
    // JSON parsing successful, continue with data processing
    var_dump($data);
}
