function foo() {

}

echo foo()[1]; # <<<

?>

Expected result:

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

Thank you for your personalised answer and taking time to read and understand my bug report.

This is obviously a bug: even the "array(1,2,3)[1]" expression cannot be parsed by PHP!

Maybe it is just a LALR parser mistake like...

stuff: [...]
     | variable '[' expression ']'

... instead of ...

stuff: [...]
     | expression '[' expression ']'


Sorry for being rude, but your copy-paste-reply make me feel my problem has been underestimated by an inexperienced person. But maybe I am wrong, then just prove me that what I am talking about is nonsense...

According to me, if I can't do "a[i]" but can do "b = a; b[i]", there is something wrong.

It's a Duplicate of bug #23022
