Marc by Marc Jacobs website PHP for MySQL code generation helper automatically generates class files based on fields in MySQL

Automatically generate class files based on the fields in Mysql:

But you need to import:

Require_once./db/ez_sql_core.php;
Require_once./db/ez_sql_mysql.php;

Help Document: Http://jvmultimedia.com/docs/ezsql/ez_sql_help.htm

：

Core code:

Copy the Code code as follows:

Class db{
