when will people learn?? the ternary operator is for CHOOSING A
VALUE. it is NOT for side effects. its precedence is designed to allow
it to be assigned, NOT to have assignments done inside.
NEVER USE ?: for side effects. ALWAYS use it to return a value chosen
from two. do not break this rule and it will always work.
$bar = ($foo == 1) ? 0 : 1 ;
that is the proper answer to the OP's question. no side effects, only
ONE use of $bar and easy to read. the () are optional but i like them to
highlight what the boolean part is.
