Mastering PHP 7

Error handling

Handling errors around PDO can be done using the special PDOException class, as follows:

<?phptry {    $host = '127.0.0.1';    $dbname = 'sakila';    $username = 'root';    $password = 'mL08e!Tq';    $conn = new PDO(        "mysql:host=$host;dbname=$dbname",        $username,        $password,        [PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION]    );} catch (PDOException $e) {    echo $e->getMessage(), PHP_EOL;}

There are three different error modes:

• ERRMODE_SILENT
• ERRMODE_WARNING
• ERRMODE_EXCEPTION

Here, we are using ERRMODE_EXCEPTION in order to utilize the try...catch blocks.
