Comment (by cogmios):

 I found out... that if I run in a PHP version < 5.4

 {{{
 $expected_array_got_string = 'somestring';
 echo $expected_array_got_string['some_key'];
 }}}

 that it returns "s"

 However starting from PHP version 5.4. it will throw: Warning: Illegal
 string offset 'some_key'

 :)

 I think that's the reason for the low amount of users seeing it...

 (see also example 2 here: http://php.net/manual/en/function.empty.php
