HI,

I want to access php function from javascript. this php function returns an array. I have to save it into a variable in javascript for further processing...
Kindly help me and guide me how i do that..

php code is:
<?php

 header("content-type: application/x-javascript");

$dirname="/myphp/MyPP";
$galleryarray = array();

    function returnimages($dirname) {

        $files = array();

        $curimage = 0;


        //valid image extensions

        $pattern="(\.jpg$)|(\.png$)|(\.jpeg$)|(\.gif$)";


        if($handle = opendir($dirname)) {


            while(false !== ($file = readdir($handle))) {

                if(eregi($pattern, $file)){

                  galleryarray[$curimage] =  $file';

                    $curimage++;

                }

            }


            closedir($handle);

        }

    }

    //Define array in JavaScript returnimages()
    //Output the array elements containing the image file names

            function rotateimages(){


        var imagesDirectory =galleryarray[curimg];

                document.getElementById("slideshow").setAttribute("src", imagesDirectory)

                curimg = (curimg < galleryarray.length - 1) ? curimg + 1 : 0

            }



            window.onload = function(){



             setInterval("rotateimages()", 900)
