There are two considerations... should the first use of the ternary operator feed the first operand of the second, or should the second use of the ternary operator feed the 3rd operand of the first use.

     $foo = ($a ? $b : $c) ? $d : $e;  // PHP does this one.

     $foo = $a ? $b : ($c ? $d : $e);

Either way... do you think the following makes for readable code? <?php

     $foo = $a ? $b : $c ? $d : $e;

When I write something like this, I expect it to happen from left to

right. Always have, always will. That said I see the 'proper' expectation of this statement:

$foo = $a ? $b : $c ? $d : $e; as: $foo will be the result of "if $a then $b else if $c then $d else $e;" Why php interprets it differently is just not logical to me. Of course

writing something like that with one set of parens solves the riddle as well as making it more readable:

$foo = $a ? $b : ($c ? $d : $e); As for ambiguity - I don't see it. Again the literal syntax of the

ternary if is (IMHO):

"if (cond) then (statement) else (other statment)" In your example:

      $foo = $a ? $b : $c ? $d : $e;

I see it exactly as this: "if $a is true then $b else

    if $c is true then
    $d
    else
    $e;"

Why should php evaluate the last statement before deciding if it even

needs that statement?
