Question

I use ternary operators alot but I can’t seem to stack multiple ternary operator inside each other.

I am aware that stacking multiple ternary operator would make the code less readable but in some case I would
like to do it.

This is what I’ve tried so far :

$foo = 1;
$bar = ( $foo == 1 ) ? "1" : ( $foo == 2 ) ? "2" : "other";
echo $bar; // display 2 instead of 1

What is the correct syntax ?

Answer 1

Those parenthesis are what I think is getting you.

Try

$foo = 1;
$bar = ($foo == 1) ? "1" : (($foo == 2)  ? "2" : "other");
echo $bar;
