Ok brett its pretty simple the difference between the two. In this
particular circumstance the two operators are used for very different
things. Example 1 is a C like operator. Almost like an object in OOP
programming.
$engine is like a pointer to the value do_themefooter($index);
returns. Which is what happens in this sense.
Example 2
This is one of many ways to populate an array in php.
Instead of populating the array with a number based index, They have
chosen to populate the array using names instead of numbers. Ex.
$array[0] = "whatever";
Ex. $array('skinid' => $skinID);
This technique is pretty frequent in certain circumstances. So
$array['skinid'] refers to the value of $skinID.
Hope this was helpful.
