Support negative indexes for arrays and strings

Hello everyone, I would like to open the discussion around the support of negative indexes, as I feel a lot of developers will benefit from this syntactical sugar. Example: $foo = array(1,2,3); echo $foo[2]; // 3 echo $foo[-1]; // 3 $bar = 'baz'; echo $foo[2]; // 'z' echo $foo[-1]; // 'z' The change to PHP is quite trivial, but as it's a change to language it needs to be discussed. I'm happy to open a RFC, I have got a wiki account but I haven't got permission to add a wiki page. Whom do I need to contact regarding getting correct permissions to add/edit wiki pages? Kind Regards Marc
