How can you troubleshoot errors related to json_encode and json_decode functions in PHP?

When troubleshooting errors related to json_encode and json_decode functions in PHP, ensure that the input data is valid JSON format.

if($encoded_data === false){
    echo "Error encoding data: " . json_last_error_msg();
}
// Decoding the input data
$decoded_data = json_decode($encoded_data);
if($decoded_data === null){
    echo "Error decoding data: " . json_last_error_msg();
}
