Having a strange behavior with Ternary Logic

Question

When I do -

echo "Hello ". (true) ? 'World' : 'XYZ';

The output - World instead of Hello World. But when -

$person = (true) ? 'World' : 'XYZ';
echo  "Hello ".$person;

The output - Hello World which is expected. Don't understand why this behave like this! Is it expected?

I assume the `"Hello "` part is considered part of the condition — ksbg, Jun 10 '15 at 08:36

echo "Hello ". (true) ? 'World' : 'XYZ';

is same as

echo ("Hello ". (true)) ? 'World' : 'XYZ';

You need:

echo "Hello ". (true ? 'World' : 'XYZ');

That means it is happening because of the operator precedence? – Sougata Bose Jun 10 '15 at 08:37
