Ternary Operator issue

Question

I was expecting the output would be:

http://domain.dev/category/123

But the actual output is: ""

$condition = true;
$categoryId = 123;
$result = 'http://domain.dev/category' . empty($condition) ? '' : '/' . $categoryId;

var_dump($result);

From what I understand - it check if empty($condition) is empty - if true then append http://domain.dev/category with '' OR else /$categoryId

What did I do wrong?

What you're actually checking there is whether `'http://domain.dev/category . empty($condition)` is "truthy" - which it always is - so the empty string is returned. — CD001, Jan 19 '17 at 11:32

just put () around statement:

$result = 'http://domain.dev/category' . (empty($condition) ? '' : '/' . $categoryId);

so it's treated as operator
