The conditional operator has higher precedence than the assignment operator, so
$c?$x='TRUE':$y='FALSE'
is the same as
($c?$x='TRUE':$y)='FALSE'

The addition operator has higher precedence than the conditional operator, so
$c?$x+2:$y+3
is the same as
$c?$x+2:($y+3)

If you want to do assignments, use if or add parens. Think of as the conditional operator as an operator that returns something.
