<?php

$json_array1=null;

$json_array2=null;

$a1=array("Peter","Quagmire","Joe");

$a2=array("Cleveland", "Loretta", "Junior");

$json_array1 = json_encode($a1);

$json_array2=json_encode($2);

?>

<script type="text/javascript">

function getarray()

{

var jsarray1= <?php echo $json_array1;?>;

var jsarray2 = <?php echo $json_array2;?>;
