Return Array Element without Creating Variable

I feel stupid for asking this cause it seems so basic but it's really bugging me.

I have a method that returns an array with a single element. I just want it to return the element not wrapped in an array. I tried this.

return $f->getValue()[0];

and it gives an error but if I save it to a variable, it works fine.

$v = $f->getValue();
return $v[0];

I can't figure it out....

Use reset(). 

<?php return reset( $f->getValue() ); ?>

Edit: reset() is probably superior to current() as it also makes sure that the internal pointer is reset, despite it not making much difference if the array only contains one element.

have you tried this

         <?php
           return array_shift(array_values($array));
         ?>

Get the first element of an array

What you are trying to do, is called array dereferencing, and is only possible in PHP as of version 5.4 (if you scroll up a few lines in the documentation article I linked to, you'll see it mentioned).

As far as I know since you are returning an array you only can get an array. You can instead save the array to a variable in the class (accessible by $f->myArray) and then return just the string portion. Or the other option is to do what your second example is and return the array and retrieve the string from it.
