• you should make json string in PHP and then json to JS object for javascript logic. json/js.html – Riz Commented Mar 12, 2012 at 10:30
• 1 This isn't hard to do (json_encode is your friend), but "more than thousands of values" suggests you might want to rethink your application architecture... – lonesomeday Commented Mar 12, 2012 at 10:30

You are looking for JSON and json_encode():

$string = json_encode($array);

The content of the string will be the array written in valid javascript.

Use JSON notation to create a string of values and then read it from JS. The simplest way to do this is something like that:

<script type="text/javascript">
var myPHPData = <?php echo json_encode($myData); ?>;
alert myPHPData; // now you have access to it in JS
</script>

if you dont intend to use json , you can do something of this kind..

you can create a string of this kind in php (separate it by any delimiter)

      $arr = "1;2;3;4;5;6;7" ;

in javascript you can convert this to array using split function

      //make an ajax call and get this string (say str)
      arr = str.split(";");

split() returns an array

 arr[0] is 1  
 arr[1] is 2
 and so on !!
