ternary operation

[Romain Quellec]

Hi.

Simple question : Can we use ternary operation with PSR-2 ? There is no specification about it.

as a reminder, ternary expression : (expr1) ? expr2 : expr3

[guilher...@gmail.com]

I normally tend to use like:

(expr)

    ? expr2

    : expr3;

I think since there's no spec that means it's to be used at your discretion.

See https://groups.google.com/forum/#!topic/php-fig/1OuwoFVqaf4 for more info.

If breaking to multiple lines, I would use a control structure.

[Benjamin Delespierre]

IMHO a control structure add more lines, deteriorate lisibility, and doesn't improve performances.

$a = (expr)

  ? $b

  : $c;

vs.

if (expr)

  $a = $b;

else

  $a = $c;

Note you can also use the contracted form of the ternary operator:

$a = $b ?: $c;

which is very practical to pick a default value.
