The only include that is different between the two environments is the addition of the Smarty Templating directory on Linux.

include_path = ".;c:\php\includes;c:\php\extras\libs;./include;C:\PHP\PEAR\pear"

include_path = ".:/usr/share/php:/usr/local/lib/php/Smarty/:/usr/share/pear/:./include"

To initialize, the connection is declared as global. In the begin_session function, the connection is set up. This connection works fine if I am just trying to read the session data, but if I try to write to the session table, the query function is unknown.

This is the Begin_Session function:
// Globals

Begin_Session($db_name, $tb_name)
	global $connection;
	global $session_table;
	$connection = new db_conn($db_name);
	$session_table = $tb_name;
	return true;
This is the Read_Session function
function Read_Session($sess_id)
	global $connection;
	global $session_table;
	$query_result = $connection->query("SELECT * FROM $session_table WHERE session_id = '$sess_id'");
	if(mysql_num_rows($query_result) == 0) 	
		return ""; // No session exists	
	else  // Session exists. Yay!			
		return mysql_result($result,0,1);
This is the Write_Session function
function Write_Session($sess_id, $add_to_session) 
	global $connection;
	global $session_table;
	$seconds = getMicroTime();    // This function just returns seconds since 1970
	$query_result = $connection->query("SELECT session_id FROM $session_table WHERE session_id = '$sess_id'");
	$add_to_session = addslashes($add_to_session);
	if(mysql_num_rows($query_result) == 0) // If no session exists, make this a new session
		$connection->query("INSERT INTO $session_table (session_id, session_variable, last_accessed) VALUES('$sess_id','$add_to_session',$seconds)");
	else // Session already exists, so update session data
		$connection->query("UPDATE $session_table SET session_variable = '$add_to_session', last_accessed = $seconds WHERE session_id = '$sess_id'");
	return true;
