CGL says (page 11):
Ternary conditional operator must be used only if it has two outcomes. 
Example:
$result = ($useComma ? ',' : '.');

so I added parantheses around the complete condition

thanks Stucki, but now it looks like this:
$result = ($useComma) ? ',' : '.';

why is this better than the parantheses around the complete condition ?
