How can the validity of JSON data be ensured before importing it into a database using PHP?

To ensure the validity of JSON data before importing it into a database using PHP, you can use the json_decode() function to check if the data is valid JSON format. If the data is not valid, an error will be thrown and you can handle it accordingly before proceeding with the import. 

$json_data = '{"name": "John", "age": 30}';
$decoded_data = json_decode($json_data);

if($decoded_data === null && json_last_error() !== JSON_ERROR_NONE) {
    // Handle invalid JSON data here
    echo "Invalid JSON data";
} else {
    // Proceed with importing the data into the database
    // Your database import code here
}
