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');

yes but i need my php to load all 6 chatrooms due to php only loads once

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);
