Hi All I Have A File Called session.php

<?php
       
	function _open() {
		
		global $_sess_db;
 
		$_sess_db = mysql_connect(CUR_HOST, SYS_USER , SYS_PASS);
		
		mysql_select_db(CUR_DB, $_sess_db);
	
	}
 
	function _close() {
		
		global $_sess_db;
 
		return mysql_close($_sess_db);
	
	}
	
	function _read($id) {
		
		global $_sess_db;
 		
		if ($db_result= mysql_query("SELECT data FROM cms_sessions WHERE id = '$id'",$_sess_db)) {
			
			if (mysql_num_rows($db_result)) {
				
				$record = mysql_fetch_assoc($db_result);
 
				return $record['data'];
			}

		}
 
		return '';
	}
	
	function _write($id, $data) {
		
		global $_sess_db;
 		
		global $id;
		
		global $data;
		
		$access = time();
 
		$sql = "REPLACE INTO cms_sessions VALUES ('$id', '$access', '$data')";
 
		return mysql_query($sql, $_sess_db);
	
	}
	
	function _destroy($id) {
		
		global $_sess_db;
 
		$sql = "DELETE FROM cms_sessions WHERE id = '$id'";
 
		return mysql_query($sql, $_sess_db);
	
	}
	
	function _clean($max) {
		
		global $_sess_db;
 
		$old = time() - $max;
		
		$old = mysql_real_escape_string($old);
 
		$sql = "DELETE FROM cms_sessions WHERE access < '$old'";
 
		return mysql_query($sql, $_sess_db);

	}
	
	session_set_save_handler('_open','_close','_read','_write','_destroy','_clean');
	
	session_start();
 	
	?>

You need to make sure that session_start is the first line in a script that uses session vars, try putting it before your functions.

You are calling a function session_set_save_handler() before the session_start() which may well be needing the session_start() to be been called first.

session_start needs to be the first line of code in any script that uses it.
