Description
Suppressing errors using an error control operator(@) is discouraged. Instead of ignoring the raised error, it should be fixed accordingly.
Bad practice
$user = ['name' => 'John', 'age' => 23];
echo @$user['city'];
Recommended
$user = ['name' => 'John', 'age' => 23];
if (isset($user['city'])) {
echo $user['city'];
}
