Since PHP 5.4 it's possible to do exactly that:

getSomeArray()[2]

You cannot use something like this :

$this->getData()['a']['b']

Youy have to use some temporary variable, like this :

$tmp = $this->getData();
$tmp['a']['b']    // use $tmp, now

In your case, this probably means using something like this :

function myfunction() {
  $tmp = $this->getData();
  return ($tmp['a']['b'] ? true : false);
}

I created the function:

arrayGet($array, $index) { return $array[$index]; }

And used it like this:

myfunction() { return '(arrayGet(arrayGet($this, "a"), "b") ? true : false)' }

Btw, there is a bug in your code: The quotes need to be escaped.

myfunction() { return '($this->data[\'a\'][\'b\'] ? true : false)'; }

If you don't want a temporary variable for that and your PHP version is less, than 5.4, than you still can use a few built in functions to get the first or the last element:

$x     = 'first?last';
$first = array_shift(explode('?', $x));
$last  = end(explode('?', $x));
$last2 = array_pop(explode('?', $x));
