Login with PHP using PDO

Question

I already know how to register, but login is a bit complicated for me. I found some materials on the internet and I would like to know what the following line does. I know I’m collecting the form information, wanted to know what you do specifically " ? $_POST['password'] : ''; " that part of the line ahead.

// resgata variáveis do formulário
$email = isset($_POST['email']) ? $_POST['email'] : '';
$password = isset($_POST['password']) ? $_POST['password'] : '';

Answer 1

That’s what we call a if ternary. What comes after the assignment (=) and before the ? is a condition for attributing what comes before or after :.

? == if
: == else

In a practical example you can have:

$minha_variavel = $se_aqui_for_verdadeiro ? $isso : $se_nao_isso;
