Just because an associative array contains 2 values/cells, it does not mean you can use array(1) and array(2) to refer to these values. It could very well be array(1234) for the 1st cell and array(2034) for the 2nd.
So unless you actually have name-value pairs and the name is not a sequential number, then using associative arrays do not make much sense.
As for the approach used. A single SQL insert select statement is a much better candidate for the problem - and will provide far better performance and significantly better scalability.
* how can i post my script in a formatted shape, which tags do i have to useYou need to use the \ tag at the start of your code block and then use an exact copy of that tag again to close the code block.
