Sorry, but your problem does not imply a bug in PHP itself.  For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system is not the
appropriate forum for asking support questions.  Due to the volume
of reports we can not explain in detail here why your report is not
a bug.  The support channels will be able to provide an explanation
for you.

Thank you for your interest in PHP.

The 'array access' syntax only works for arrays and strings, strings also got curly braces: $str{0} to access a certain byte index in that string.

So yes, this is intended, as the behavior for usage on other types are undefined.
