Here is my sample code:

require "include/connection.php";
//$menu_name=$_GET['menus'];
//$menulist= array("Peter", "Joe", "Glenn", "Cleveland");
//reset($menulist);
$menulist=array();
$q="select name from menus";
$result=mysql_query($q);
while($row=mysql_fetch_array($result)){
$name=$row['name'];
array_push($menulist,'$name');
}
?>
<script type="text/javascript">
var menu1=new Array()
.............//I want to copy array menulist to menu1,how to program here?I want the menu1 to be the same as menulist

Hello,
you could use json_encode() to encode your array in php to the json format and then print it out from php inside the html, then decode the array using js's json functions.
But as long as you do that you could print it straightforward, just write from php the "html" code that defines the array in js.

+1 for json... below is what you need to do:

<script type="text/javascript">
var menu1= eval( '(' + <?php echo json_encode($menulist); ?> ')' );
</script>

Whoops.... it's a bit late.  You don't even need to bother with the
eval stuff.  using eval becomes important when you are using the
xmlHTTPRequest.

just:
<script>
var menu1 = <?php echo json_encode($menulist); ?>;
</script>
