Question

I’m using a PHP framework that returns SQL results as iteratable objects. Problem is I have a SQL query that that returns one row and I don’t want to have to create a foreach-loop to get at the first – and only – element.

So how do I do it?

These don’t work:

$obj->item(0)->propName;
$obj->next()->propName;
$obj[0]->propName;

Any ideas?

Assuming by “iterable”, you mean that the object implements the Iterator interface, you can use $obj->current() to retrieve the current element, so $obj->current()->propName is probably what you want.

If the iterator pointer has been moved (for example, if it was used in a foreach, which doesn’t reset the pointer), then you can call $obj->rewind() to set the pointer back to the first element before you call $obj->current().
