PHP cannot call javascript functions. PHP is ran on the server and Javascript in the browser. PHP can only output javascript.

 

I think this line

var dc_chatroom_id = <?php echo $chatroom_id = document.getElementById('id'); ?>;

needs to be

var dc_chatroom_id = document.getElementById('<?php echo $chatroom_id; ?>');

Example output of above line would be like the following if $chatroom_id is set to 1

var dc_chatroom_id = document.getElementById('1');

PHP can't do that, it doesn't know what javascript is. You can only get PHP to output the necessary javascript code that loads the chat rooms.

 

You can do a for loop loop that outputs the javascript code needed for the chatrooms

eg

for($i = 1; $i <= 6; $i++)
{
   // target chatroom
   echo "var dc_chatroom_id = document.getElementById('$i');";

   // load the chatroom
   echo "javascript_function_that_loads_chatroom(dc_chatroom_id);"
}

But If you're doing that then you may as well handle this with javascript and not PHP. The above PHP code will output the following javascript code

var dc_chatroom_id = document.getElementById('1');
javascript_function_that_loads_chatroom(dc_chatroom_id);
var dc_chatroom_id = document.getElementById('2');
javascript_function_that_loads_chatroom(dc_chatroom_id);
var dc_chatroom_id = document.getElementById('3');
javascript_function_that_loads_chatroom(dc_chatroom_id);
var dc_chatroom_id = document.getElementById('4');
javascript_function_that_loads_chatroom(dc_chatroom_id);
var dc_chatroom_id = document.getElementById('5');
javascript_function_that_loads_chatroom(dc_chatroom_id);
var dc_chatroom_id = document.getElementById('6');
javascript_function_that_loads_chatroom(dc_chatroom_id);
