Question

I have 2 pages, one PHP and one Javascript.
I’d like to pass the variable from this PHP script on one page:

$strFind="SELECT * FROM  cometchat_chatrooms_users WHERE userid=$curmemid";
$result=mysql_query($strFind) or die(mysql_error());
$row=mysql_fetch_array($result);
$room=$row['chatroomid'];

to this Javascript on another page:

var timestamp = 0;
var currentroom = $room;
var heartbeatTimer;
var minHeartbeat = 3000;
var maxHeartbeat = 12000;

How can I do this?

You cannot actually “pass” a variable anywhere. But only a scalar value. Frankly, you can pass only text data.
So, in case of javascript you have 2 options:

1. To generate whole js code from PHP along with all it’s variables. Much like to how you generate HTML.

2. To request some variable from JS running in a browser, using AJAX technique.
