Mastering PHP 7

Error handling

Handling errors is pretty straightforward with the try...catch blocks, as MongoDBDriverExceptionException is being thrown whenever an error occurs:

<?phprequire_once __DIR__ . '/vendor/autoload.php';try {    $manager = new MongoDBDriverManager('mongodb://localhost:27017');} catch (MongoDBDriverExceptionException $e) {    echo $e->getMessage(), PHP_EOL;    exit;}
