So use the client-side loop to build a two-dimensional array of your arrays, and send the entire thing to PHP in one request.

Server-side, you'll need to have another loop which does its regular insert/update for each sub-array.

You could use JSON stringify array  to encode your array in JavaScript  and then use  array json decode   POST  jsondata     in your PHP script to retrieve it

AJAX requests are no different from GET and POST requests initiated through a  lt form gt  element  Which means you can use   GET and   POST to retrieve the data   When you re making an AJAX request  jQuery example       JavaScript file  elements    1  2  9  15  join        post   test php    elements  elements     It s  almost  equivalent to posting this form    lt form action   test php  method  post  gt     lt input type  text  name  elements  value  1 2 9 15  gt   lt  form gt    In both cases  on the server side you can read the data from the   POST variable      test php file   elements     POST  elements     elements   explode       elements     For the sake of simplicity I m joining the elements with comma here  JSON serialization is a more universal solution  though
