Javascript array from php array

[mielke]

I've been using the following code to create a one dimensional javascript array from a php array, and it has been working great...

var js_array = new Array();
js_array = [' . ($php_array ? '"' . implode('", "', $php_array) . '"' : '') . '], i;

how can I append the above code to work for a multidimensional array.

Thanks for any suggestions

i haven't worked with php in a while; provide an example of a sample multidimensional php array AFTER it's been added to a webpage. using that as a template, it can be formed into JS.

this works perfect for a 1-D array...

<?php
$php_array = array('a',0,1);
echo '

function print_array()
{
var js_array = new Array();
js_array = [' . ($php_array ? '"' . implode('", "', $php_array) . '"' : '') . '], i;

for(var i = 0; i <= 2; i++)
{ alert(js_array[i]); }
}

';
?>

so my questions is how to structure the implode statement for a 2-D array...

<?php
$php_array = array(array('a',0,1),array('b',0,1));
echo '

function print_array()
{
var js_array = new Array();
js_array = [' . ($php_array ? '"' . implode('", "', $php_array) . '"' : '') . '], i;
for(var i = 0; i <= 2; i++)
{ alert(js_array[i]); }
}

';
?>

Use json functions from PHP.

$array = array(
        array(1, 2, 3, 'a'),
        array(4, 5, 6, 'b')
    ); 

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

http://uk3.php.net/json_encode

This worls with n-dimesional arrays. If you set keys, the array will be transformed into an object.

Thanks Hyperion that worked great.

learned something knew. i didn't know that PHP knew how to return JSON.

i know at this point, it will be a dead issue to you mielke, but what i meant for you to do is to show me the OUTPUT of one of your multidimensional arrays, not the PHP code to create/access the array.

This is the output of the above function

var js_array = [[1,2,3,"a"],[4,5,6,"b"]];

exactly what i would have been looking for in mielke's second post had i needed to proceed without the json_encode knowledge i just gained.
