Which coding style you use for ternary operator? [closed]
The ternary operator is generally to be avoided, but this form can be quite readable:
result = (foo == bar) ? result1 : (foo == baz) ? result2 : (foo == qux) ? result3 : (foo == quux) ? result4 : fail_result;This way, the condition and the result are kept together on the same line, and it's fairly easy to skim down and understand what's going on.
I try not to use a ternary operator to write nested conditions. It defies readability and provides no extra value over using a conditional.
Only if it can fit on a single line, and it's crystal-clear what it means, I use it:
$value = ($a < 0) ? 'minus' : 'plus';
Personally, I only use the ternary operator if it fits on one line. If it need to span, then it's time for the good old
