Question

The title seems confusing but this is my first time using ternary conditions. I’ve read that ternary is meant to be used to make an inline if/else statement. Using no else is not possible. Is it true?

I want to change this with ternary condition for practice

if (isset($_SESSION['group']
{
if ($_SESSION['item'] == 'A')
{
echo "Right!";
}
}

It has two if statements only. The second if is nested with the other. I’ve also read that to make a no else possible for ternary, it just have to be set to null or empty string.

It’s a bad example because you can use an AND-operator on the nested if:

$result = isset($_SESSION['group'] && $_SESSION['item'] == 'A' ? true : false;

Of course you can nest ternary operator, too:

$result = isset($_SESSION['group'] ? ( $_SESSION['item'] == 'A' ? true : false ) : false;

with echo

echo  isset($_SESSION['group'] ? ( $_SESSION['item'] == 'A' ? "Right!" : "false" ) : "false";
