Description:
------------
If you try within a return construct to attach a variable to an array, the array will be overwriten by the value you tried to attach to it. Because the following examples work, it should also work with test script due to consistency.

$ php -r 'function foo() { $intNumber = 0; return $intNumber + 1 + 2; } var_dump(foo());'
int(3)

$ php -r 'function bar() { $strText = "foo"; return $strText . "bar"; } var_dump(bar());'
string(6) "foobar"

Test script:
---------------
$ php -r 'function foo() { $arrFoo = array(); return $arrFoo[] = "foo"; } var_dump(foo());'

Expected result:
----------------
array(1) {
  [0]=>
  string(3) "foo"
}

Actual result:
--------------
string(3) "foo"
