PHP question mark operator and string concatenation

Question

I'm still a newbie in php and I'm using codeigniter for my backend framework. I have a table.php file that will generate a html table in real-time. Then, I encounter some issues.

$output_string .= "<td>".($row->isactive == "0") ? "Activated":"Deactivated"."</td>";

with the above code I get nothing, but with a little change to:

$isactive = ($row->isactive == "0") ? "Activated":"Deactivated";
$output_string .= "<td>".$isactive."</td>";

I get my results, so my question is, why?

Doesn't PHP support question mark operator in string concatenation??

Answer 1

It does support it, just put some parenthesis around it:

$output_string .= "<td>".(($row->isactive == "0") ? "Activated":"Deactivated")."</td>";
