"Guard" operator like JavaScript in PHP -

-

i in javascript:

function (a, b, c) {     var foo = || b || c;     return foo.bar; }

is there quick way assignment fallback or require custom function?

php 5.3 introduces ?: operator (not confused ternary conditional, go figure). don't use php, imagine it'd like:

 $foo = $a ?: $b ?: $c

see: http://php.net/manual/en/language.operators.comparison.php

since php 5.3, possible leave out middle part of ternary operator. expression expr1 ?: expr3 returns expr1 if expr1 evaluates true, , expr3 otherwise.

happy coding.
