PHP Shorthand Ternary not behaving as expected -


introduced in php 5.3, shorthand ternary operator should work this:

$result = 'foo' ?: 'bar';

should return foo. however, on live server (php 5.4.26), result bar.

a full ternary operator syntax works fine.

$test = 'foo'; $result = $test ? $test : 'bar';

returns foo correctly. both syntaxes fine on dev server (php 5.3.10).

is there way disabled somehow? suggestions?

changing instances full systax undesirable - there's significant number in external library (amazon aws sdk).

correction:

$result = 'foo' ?: 'bar';

does have correct result on both servers, but

$test = 'foo'; $result = $test ?: 'bar';

incorrectly returns bar on live server. wierder...
