RE: [PHP] Cacheing data form PHP script

Here is my final layout, i still yet to test it on the production machine being a dual 2G xeon, has had major performance issues generated list menus onto the screen and load time. function asset_type_list2($tID=null,$tab_index = null,$cache_data = null,$disabled = null) { global $db; if ($cache_data) { $query = $db->check_menu_cache ('asset_types','asset_type'); } else { $query = "SELECT SQL_NO_CACHE asset_typeID,asset_type FROM asset_types ORDER BY asset_type ASC"; } return $db->get_menu2('asset_typeID',$query,set_menu_extras ($tab_index,$disabled),false,$tID,false,CACHE); } and in the db class function check_menu_cache($table,$value_field) { $query = $this->query("SELECT SQL_CACHE cache_data FROM cache_menu_table WHERE cache_table='$table'"); if ($this->results()) { $query = "SELECT SQL_CACHE cache_data FROM cache_menu_table WHERE cache_table='$table'"; } else { $query = $this->query("SELECT SQL_NO_CACHE * FROM $table ORDER BY $value_field ASC"); while ($row = $this->fetchArray($query)) { $arr[$row[0]] = $row[1]; } $insertID = $this->insert("INSERT INTO cache_menu_table (cache_data,cache_table) VALUES ('".serialize ($arr)."','$table')"); $query = "SELECT SQL_CACHE cache_data FROM cache_menu_table WHERE cacheID IN (".$insertID.")"; } return $query; } What is the purpose of mysql_unbuffered_query i just tried it and killed my connection
