That's strange. I do that all the time, I just use json_encode and
pass the data to a Javascript function. And this is data including
points, html, and all kinds of other things. It always gives me the
correct length. I've found it to be a very simple and efficient way to
pass data.
You may want to do a print_r and make sure the indexes of the arrays
you are passing in all are sequential and start with zero.
Could you describe what you mean by this?
"I transform $points in array: $myarray"
What exactly are you "transforming?"
