I'm using a template engine that inserts code in my site where I want it.
I wrote a function to test for something which is quite easy:
myfunction() { return '($this->data["a"]["b"] ? true : false)'; } The problem is, $this->data is private, and I can't access it everywhere, so I have to use getData(); which causes my problem.
$this->getData()['a']['b'] does not work, and assigning the value first doesn't either because it will be used directly in an if() block.
Any ideas?

In PHP you can return one and only one value from your user functions, but you are able to make that single value an array, thereby allowing you to return many values.
C programming does not allow to return an entire array as an argument to a function. However, you can return a pointer to an array by specifying the array's name without an index.
The count() function returns the number of elements in an array.
A function can return a value using the return statement in conjunction with a value or object. return stops the execution of the function and sends the value back to the calling code. You can return more than one value from a function using return array(1,2,3,4).
Since PHP 5.4 it's possible to do exactly that:
getSomeArray()[2] Reference: https://secure.php.net/manual/en/language.types.array.php#example-62
On PHP 5.3 or earlier, you'll need to use a temporary variable.
