So I have an array of records retreived from a database. The array is in the format;

$rows[0]['id']=1; $rows[0]['title']='Abc'; $rows[0]['time_left']=200;   $rows[1]['id']=2; $rows[1]['title']='XYZ'; $rows[1]['time_left']=300; //And so on upto 10-20 rows

What’s the best way of transferring this array over to my javascript code? I’d like the javascript to be able to loop through all of the records, and using the ‘id’ attribute, update the div with that id with some information.

My javascript code is in an external .js file, but i’m able to execute php code in the HTML code of my page. So I could do something like this:

In my_file.js:

var rows=New Array();

In HTML code:

<html> <head> <script type='text/javascript' src='js/my_file.js'></script>  <script type='text/javascript'> <? foreach ($rows as $row):?> <? extract($row);?> rows[<?=$id;?>]['title']='<?=$title;?>'; //And so on <? endforeach;?> </script>

  1. I tend to use a JSON object for this:

    • On the server side, JSON encode your data: json_encode($data);
    • On the JavaScript side, I write a function that takes a JSON object as a parameter and unpack it.

    When you unpack the object, you can print the array’s contents into a <DIV> tag, or where ever you would like on the page (jQuery does a pretty sweet job of this).
