Thanks for your research Mike, i'm a bit puzzled.
I have a custom random-array generator that i use to fill the
available memory to it's max, about 1.5G on a 2G system, then passing
it to a recursive json string generator.
Not passing by reference did double my memory requirements, but i've

What about using the right type of quotation marks for output:
I use double quotes() if I expect to output variables within the

And for the most part, you'd be right but it still isn't good
practice to *not* teach something strictly because it's not entirely
significant.

I'd like to add that when dealing with large memory structures,
usually arrays, combining them is fastest when done like this:
$array1 += $array2;
This will not always produce correct results when dealing with arrays
that contain identical keys, but for non-overlapping arrays it is far
faster
