How to return an array from an AJAX call

Question

I m searching for a better solution to making an AJAX call with jQuery  having the PHP file return an array  and have it come out client-side as a Javascript array  Here is what I have been doing this   PHP File  Example php       lt  php      id numbers   array  NES-ZL   NES-AL   SNS-ZL         for   i 0   i lt count  the array    i             echo  id numbers  i           echo              gt    JS File     id numbers   new Array      ajax       url  Example php       type  POST       success function msg           id numbers   msg split                   My current method is just a little too convoluted for my taste   What I d like to do is to be able to just  return  id numbers    on the PHP side and directly translate it to a Javascript array after the AJAX call   Ideas  anyone

Have a look at json encode  http   php net manual en function json-encode php   It is available as of PHP 5 2  Use the parameter dataType   json  to have it parsed for you  You ll have the Object as the first argument in success then  For further information have a look at the jQuery-documentation  http   api jquery com jQuery ajax

Xeon06  nice but just as a fyi for those that read this thread and tried like me    when returning the array from php    json encode  theArray   converts to a string which to me isn t easy to manipulate esp for soft js users like myself   Inside js  you are trying to get the array values and or keys of the array u r better off using JSON parse as in var jsArray   JSON parse data  where data is return array from php  the json encoded string is converted to js object that can now be manipulated easily   e g  foo  one 1  two 2  three 3  - gotten after JSON parse  for  key in foo   console log  foo    key        foo key     - prints to ur firebug console  voila

Use JSON to transfer data types  arrays and objects  between client and server   In PHP    json encode json decode   In JavaScript    JSON stringify JSON parse   PHP   echo json encode  id numbers     JavaScript   id numbers   JSON parse msg     As Wolfgang mentioned  you can give a fourth parameter to jQuery to automatically decode JSON for you   id numbers   new Array      ajax       url  Example php       type  POST       success function msg           id numbers   msg             dataType  json
