This is a huge WTF. and the following should also behave the same: $a = 'foo'; echo $a[2]; echo $a['2']; echo $a['2 cats']; because this is how the type juggling works in php: http://php.net/manual/en/language.types.type-juggling.php if we allow strings to be used as indexes for strings, we have to be consistent with what we have already. -- Ferenc Kovács @Tyr43l - http://tyrael.hu
