I have a function returning an array: function foo(){ return array('foo'=>1,'bar'=>2); }

Can I access an element of the return array without assigning it to a temporary varia开发者_开发问答ble first (e.g. foo()['bar'])?

The following example returning an object works like a charm:

function foo(){ return (object) array('foo'=>1,'bar'=>2); }
echo foo()->bar;

No, unfortunately PHP's grammar doesn't allow this. There is no good reason for this btw (there are a few discussions about it on PHP mailinglists).

If you really want it, you could consider switching to Python - it not only supports inline access to returned arrays but also many other nice things. ;)
