Ternary operator to change class

Question

I have:

 echo '<ul id="my-list" class="'.(true) ? 'classA' : 'classB'.'">';

But the HTML is not being output, only the text classA is being outputted to the page.

Where am I going wrong?

Answer 1

Try to use additionnal parenthesis :

echo '<ul id="my-list" class="'.((true) ? 'classA' : 'classB').'">';

Because the concatenation operator( like the majority of operators in php) will cast the object to its right to the same type as the object on its left .
