Parse error on explode('-','foo-bar')[0] (for instance)

Why doesn't 开发者_StackOverflow社区php support this syntax:

$s = explode('-', 'foo-bar')[0];

?

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’);

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 !
