It's a limitation in the PHP parser. There's no reason why it can't support this form of reduction, it just doesn't.

You can write it using list:
list($first_value) = explode(‘-’,‘foo-bar’);

Yes, of course, but I was just wondering why it doesn't work in the case of php – lost3den Mar 07 '10 at 15:58

The syntax ‘foo-bar’)[0] is wrong as far as php is concerned. I don't know which language you have seen such thing in but PHP has no implementation for such syntax. However, you can split your string like this:
explode(‘-’, ‘foo-bar’);

Instead you could use this if you'r force to use inline : substr($var,0, strrpos($var,'-')); But I prefer the list solution , it's more elegant !
