Placing PHP array values into a javascript array?

Question

4

Is these a way i can loop through a PHP array and have the data outputted into a JavaScript array?

For example, the JS script below will not work

var mon_Loop = <?php echo $rowCount_Mon ?>;
var mon_Events = new Array();
for(i = 0; i < mon_Loop; i++)
{ 
   mon_Events[i] = <?php $divMon[i] ?>
}

I Know its because the "i" is not a php variable so therefore invalid inside the php section, but its just an way to show what i would like to achieve. The $rowCount variable count the number of rows and is then used to for the loop. Lets say, for example that I want to place the contents of the PHP array "$divMon[0]" into the javascript array mon_Events[0].

I know that i can do it manually, like below

mon_Events[0] = <?php echo $divMon[0] ?>

But i have lots of these and therefore need the loop, Is there some JS or PHP that could do this?

Cheers.

Since it seems that your array $divMon contains numeric indexes, you can simply serialize it using json_encode:

var array = <?php echo json_encode($divMon) ?>;

Plus use the JSON_HEX_TAG argument if you are inside a <script> block, to prevent any </script> sequences from prematurely ending the script. – bobince May 17 at 1:34
