易于使用的PHP类

I have written a php class for accessing MySql. The class is very easy to use (and very intuitive). This is how to insert a new record ``` $db = new db(); $db->table = "employee" // set table name $db->field["name"] = "tanin"; // set the field "name" $db->field["lastname"] = na nakorn"; $db->field["employee_id"] = "283581"; $new_id = $db->insert(); // do the insert transaction, the function return the primary key of the new record ``` This is how to update a record ``` $db = new db(); $db->table = "employee" // set table name $db->field["name"] = "tanin"; // set the field "name" $db->field["lastname"] = na nakorn"; $db->where["employee_id"] = "283581"; // set the where clause of sql $num_rows = $db->update(); // do the update trans
